This are all safe for work. Even if I have written smut before in this book, not safe for work headcanons make me embarrassed. sns.

——————————————————————

Normal Kazuichi Headcanons
(Definitely didn't steal these from my friend—)
(sns Ko)

- He/they pronouns, but is also considering neopronouns. He is also bisexual with a female lean.

- Sometimes he forgets to take out his contacts when he falls asleep, so when he wakes up his eyes,, just,, dies.

- Undercut Kazuichi. I don't know what the fuck you may think you know, but it's canon.

- Actually pretty strong, because Ultimate Mechanic shit,, he's just a pussy. So it's hard to tell. He's fucking scared of little hamsters of course they don't  seem strong.

- Definitely was sexually attracted to tanks in high school. (Don't ask questions. fykyk)

Normal Fuyuhiko Headcanons

- Mostly uses He/him, but wouldn't get mad if They/them is used for him. I headcanon him as mlm (but in denial for a while. gay and homophobic-).

- He just seems like he would wear smudged eyeliner. It's just gonna be canon now. I said so. (Something to go along with this,, he started to wear smudged eyeliner once Natsumi would force him to allow her to do his makeup. You can not tell me that never happened I'm not believing you if you say otherwise.)

- Can't tie his shoes. None of his shoes have laces. He can't even tie his own tie. Peko does that.

- He definitely had one of those candy bracelets during every class. And he was able to role up his sleeves enough to hide it so no one knew.

- During his highschool years ya boy would pay Natsumi to buy him stuffed animals because he just liked them and at the same time didn't want anyone to see him buying them.

Highschool relationship headcanons

- Fuyuhiko caught feelings first, but also didn't know exactly what he was feeling. At the beginning he just thought he wanted to be bestest friends with Kazuichi. That was until he started having dreams about kissing him and he realized it was more than that.

- After Gundham and Sonia became official, Kazuichi realized his feeling for Fuyuhiko. But unlike him, he immediately know that he had a huge ass crush on him (mostly from when he 'liked Sonia', he would catch himself thinking more about baby gangster.)

- The first person Fuyuhiko told was Hajime, on accident. Surprisingly the first person Kazuichi told was Hajime too (intentionally). Hajime went to go tell Peko and they started playing matchmaker.

- They both would try to push the other two closer together. Forcing them to work together and eat lunch together. Peko even started to take after school classes just so Fuyuhiko and Kazuichi could walk home together.

- It was also painfully obvious that they liked eachother. Fuyuhiko was a lot more nicer to him and blushed almost every time they talked. Kazuichi would painfully flirt and compliment Fuyuhiko, however Fuyuhiko never understood his flirting.

- Everyone in their class know they liked eachother instead of themselves. Ugh stupid gays 🙄

- After about 6 months of realizing his feelings for Kazuichi, Fuyuhiko decided he wanted to confess. It took him 2 months with deciding how he was going to do it to make sure it was perfect. Spoilers: it wasn't.

- Fuyuhiko wanted to confess to Kazuichi at a park. He had flowers, food prepared, like,, tons of letters, and he even brought him a necklace. He was ready. He asked Kazuichi to meet him there and everything. However that day it rained. And it ruined his whole set up. The flowers were ruined. The letters and food was soaked. The only thing that was alright was the necklace. And while it looked a complete mess, Kazuichi was still on his way there. Oh Fuck.

- Kazuichi came to the park completely confused. Fuyuhiko could barely explain himself because he was that embarrassed. After around 12 attempts, he managed to explain it clear enough for Kaz to understand that it was an attempted confession. Of course Kazuichi accepted it and thought what the other tried to do adorable.

- They didn't even tell anyone about their relationship until about a month in. They were pretty good at hiding it too, people just thought that they still were just crushing on eachother.

- Just like before, Fuyuhiko was the one that accidentally told everyone. Kazuichi kept annoying him on purpose at lunch, with everyone there. And Fuyuhiko said (yelled) " Sometimes you make me wonder why I asked you out" (dw they often talk like that.) and Kazuichi just busted out in laughter. Word got around quickly.

Now the actual in relationship hcs

- Even before their relationship, Fuyuhiko would always make Kazuichi's lunch since he ofte forget it at home (But then you have Fuyuhiko never bringing his own lunch to school 🙄)

- Kazuichi helps Fuyuhiko with math and Fuyuhiko helps him with history. The two classes they're terrible at.

- Fuyuhiko prefers to hang out at Kazuichi's house because he doesn't want Kazuichi to be in any sort of danger nor see his family fight because of his own history with it.

- Oh yea,, Fuyuhiko is extremely overprotective with Kazuichi. He doesn't like people being rude to him. He will fight whoever he needs to.

- They went on a lot of dates to the local arcade. They both didn't know how to plan them, so that was the best option. They really enjoyed it though.

- Kazuichi has always been a huge flirt, so he definitely flirts with fuyuhiko every day. And he knows exactly what to say for a reaction out of him.

- They didn't kiss until a few weeks into the relationship. They just didn't know how to do it yet.

- Fuyuhiko loves going to Kazuichi's workplace to just keep him company. He always brings Kazuichi a snack and they usually just talk about anything.

- They didn't go to prom. Even if fuyuhiko agreed, Kazuichi knew how he felt about huge gatherings (huh.) and didn't want him to feel uncomfortable. They had a sleepover at Kazuichi's place and just stayed up all night watching movies and cuddling.

- They always talked about their future together. They've discussed moving in together after college and even vaguely discussed getting married. However every time it gets to talking about kids they just end the conversation.

Adult Headcanons

- They did go to the same college, but they didn't have the same dorm. Fuyuhiko didn't have a dormmate and Kazuichi was with Gundham (he hated it). He mostly just stayed with Fuyuhiko.

- Kazuichi always snuck into the other's room at night. He just likes to fall asleep beside him.

- Fuyuhiko often skipped his classes to be able to meet up with Kazuichi when he got out of his own. Kazuichi didn't realize he was doing this for a whole semester.

- After college they made plans immediately to get an apartment together. (close to Kazuichi's workplace ofc)

- Kazuichi doesn't let Fuyuhiko drink. He's a lightweight and one glass can make him too drunk to stand. Kazuichi found this out the hard way.

- Since Fuyuhiko can work from home, he doesn't need to get up in the morning. He also can go to Kazuichi's job in the middle of the day just to give him a kiss.

- Spooning depends on the day and the mood, but Fuyuhiko is mostly big spoon.

- Fuyuhiko always is there for Kazuichi whenever he starts panicking or crying. Sir will put on his favorite movie, get him some snacks, and just hold him until he's feeling better.

- However Fuyuhiko refuses to cry infront of really anyone, so it's really rare for him to have to do that for Fuyuhiko.

- They bake every sunday to Fuyuhiko's request. But mostly Fuyuhiko. Kazuichi will burn things down.

- Fuyuhiko can go hours listening to Kazuichi just nerd out. He loves the sound of his voice.

- Kazuichi knows how to make breakfast. That's literally all he knows how to do in the kitchen. And he makes the other breakfast every morning.

- Around 3 years into living together they both started thinking of marriage seriously, and oh boy did it happen weirdly.

- They basically proposed to eachother at the same time.

- Let me explain

- Fuyuhiko wasn't the best at planning. You could probably tell by the way he asked him out. But he did get a really nice ring for him with Ibuki's help. Then he spent months in trying to figure out what to say.

- Kazuichi on the other hand was better, but a lot more nervous. He spent months saving up for the perfect ring for him and he had actually already planned everything out from when and where to what he was going to say. He just got extremely paranoid with if he was even going to be able to ask.

- Kazuichi asked Fuyuhiko to come to a restaurant with him. This wasn't unusual, because some days they would just go out to eat to get out of the house.

- They both had their rings on them. Fuyuhiko just carried his around everywhere, waiting on the perfect moment. Kazuichi just knew that it was gonna be the night.

- So basically the night was going great, a lot better than usual. They were just in a great mood. And right before Fuyuhiko could say anything, Kazuichi asked him first.

- Fuyuhiko was shocked- Like really shocked. He didn't say anything for,, a while to the point where Kazuichi almost thought he was going to say no. But Fuyuhiko just showed Kazuichi the ring he brought and that pretty much answered for him.

- Aye but they did get free dessert

- Since they're both kinda workaholics, they both take a day off from each week to go in a date night.

- Fuyuhiko has many scars on his body dating back to when he was a toddler, and sometimes Kazuichi would ask Fuyuhiko how he got them and listen to the stories.

- Now i'll talk about the wedding

- Neither of them planned most of it. If it was up to Fuyuhiko, he believed everything would go wrong. If it was up to Kazuichi, it would also just go wrong. It was mostly Kazuichi and Peko though, with some Fuyuhiko (his choice).

- They didn't figure out who was going to walk down the aisle until the last minute. Like,, in the month. It ended up being Fuyuhiko only because Kazuichi wanted to see him in a white suit instead of a black one; something he always wears.

- The wedding day was,, something

- Um

- They were both scared. Really scared. Kazuichi kept thinking that Fuyuhiko would run off. Fuyuhiko didn't think Kazuichi would say "I do". It was sad.

- However the wedding went smoothly. For the most part. Peko walked Fuyuhiko down the aisle, and that was the first time people actually saw her cry. Oh and Fuyuhiko and Kazuichi were definitely crying. So much that there were pauses in between the service.

- Rigmt before they kissed, Fuyuhiko wiped off Kazuichi's lips. Why? Because he could smell the Coca-Cola lip balm on him and he never liked it. Embarrassing

- Anyways it was cute and whatever. Very gay. Moving on.

- After they got married it was basically like they were dating, just with a ring. Nothing changed.

- Time for some small headcanons during marriage life.

- Ever since they got married, Kazuichi has a habit that when he wakes up the first thing he'll do is take Fuyuhiko's hand (the one with the ring), and kiss it. Fuyuhiko doesn't really know because he sleeps in.

- Fuyuhiko barely addresses him as Kazuichi now. It's just "My husband" so people won't forget.

- Before they got married, Fuyuhiko wasn't too keen on public affection. Not anymore. Definitely.

- They have so many days when they just lay around the house underneath eachother. When they both have days off at the same time they just don't want to separate. I lm serious. If one of them has to go to the bathroom the other would stand outside the door.

- From when they were 3 months into the marriage they talked about renewing their vows ONLY for them to wear dresses together the second time around.

- Kazuichi always brings up adoption atleast once a week. Fuyuhiko has the same answer everytime "I'll think about it". He's just scared that he'll be a shitty father. Kazuichi has to reassure him.
