( at the penthouse)

Yn walking down stairs to find her unnie cooking in the kitchen.

Yn - good morning unnie.

Inah - good morning baby have you slept well?

well yn doesn't let anyone call her baby except her unnies

Yn - it was good.

Inah served the breakfast at the table.

In ah - so I didn't ask you anything because you look down last night but , will you tell me now what happened there yesterday?

Yn - ( munching on her food) ok, first thing the food is amazing and second ( sigh) miss Lee has a boyfriend.

Inah chocks

In ah - WHAT DID YOU JUST SAY??? SHE CALLED YOU THERE JUST TO TELL YOU THAT SHE HAS A BOYFRIEND??? ( yelling)

Yn - yaa unnie why are you yelling early in the morning?

Inah - sorry, but she called you to say only that?

Yn - yeah, and she told me go to his house with her tomorrow.

Inah - are you going?

Yn - of course she is my mother and I have to see what kind of guy she is seeing and I can't just leave her like that, I have to see whether he will keep her happy or not even though I don't care about her I need to see this things.

Inah - oh I see. You said that you don't care bout her at all but ( gets cut off)

Yn - I still don't care about her. She gave birth to me raised me for 10 years and even after she sended me to America she still sended me money so that I can study and I have a nice life.

So I have to return what the favours she did all these years.

Inah - oh I see. By the way, aren't you going to the university?

Yn - yes, I talked to them I have to go there today to fill some forms up and from tomorrow I can start going to the classes. .... Ok so I'll get ready and get going.

Inah - ok

Inah - ohhu baby you are looking hot.

Yn - you know that i am hotter than hell ( wink)

Inah - ok if you are done then go.

Yn - ok bye see you later.

Everyone was looking at her and whispering but yn being yn, she didn't gave a fuck and walked towards the principal's office and did some paperwork. By the time she was done it was already lunch time.
