You had always been the ray of sunshine in Tanjiro Kamado's life, a constant source of warmth and joy amidst the darkness of his world. From the first moment he laid eyes on you, he was completely captivated by your radiant smile and kind heart. Every little thing you did, every word you spoke, he found himself fixated on you.

   As a fellow Demon Slayer, you and Tanjiro had shared numerous battles together. Through the trials and hardships, you had become not only a trusted ally but a dear friend to him. Yet, for Tanjiro, his feelings for you ran deeper than friendship. He was undeniably lovestruck.

   It was in the gentle moments, after a grueling fight, that Tanjiro found himself stealing glances at you, admiring your determination and strength. He loved how your eyes sparkled with passion, how your laughter could light up even the darkest corners of the world.

   In the quiet of the night, as the campfire crackled and the stars adorned the sky, he would catch himself watching you intently. The way you would close your eyes and take in the peacefulness of the moment, the small smile that played on your lips as you hummed a soothing tune—it was all enchanting to him.

   But Tanjiro was also painfully aware that you were constantly surrounded by people who admired you. Your companions valued you for your skills, your kindness, and your unwavering determination. He couldn't help but feel a pang of jealousy whenever he saw someone else receive your attention or praise.

   As the days went by, his feelings for you only grew stronger, and he found it increasingly difficult to hide his adoration. In battle, he would protect you fiercely, fighting with all his might to keep you safe. But he knew that there was something more he wanted to protect—your heart.

   One evening, as the sun dipped below the horizon and the camp settled into a peaceful slumber, Tanjiro found himself sitting by the fire, unable to sleep. You were resting nearby, and he couldn't resist the urge to be closer to you.

   Quietly, he moved closer, taking a seat beside you. He watched your chest rise and fall with each breath, mesmerized by the tranquility that surrounded you even in sleep. He reached out and gently brushed a strand of hair away from your face, his heart swelling with affection.

   "Tanjiro?" you murmured, stirring from your slumber, your eyes fluttering open to meet his gaze.

   "I-I'm sorry if I woke you," he stammered, a faint blush creeping across his cheeks.

   You smiled, sitting up a bit and patting the spot beside you. "It's okay. I'm glad you're here."

   He hesitated for a moment before settling down next to you, his heart pounding in his chest. The warmth of your presence made him feel both comforted and nervous at the same time.

   "Tanjiro, is something on your mind?" you asked gently, noticing the slight tension in his shoulders.

   He took a deep breath, summoning the courage to speak his truth. "Yes, there is. I-I want to tell you something, but I'm not sure how to say it."

   You turned to him, giving him your full attention. "You can tell me anything, Tanjiro. I'm here for you."

   With your reassurance, he felt a weight lifted off his shoulders. "I... I've been in love with you for a while now. Ever since we first met, I couldn't stop thinking about you. You're always on my mind, and I can't help but feel this overwhelming desire to protect you and keep you safe."

   Your eyes widened in surprise, and for a moment, he feared he had overstepped his boundaries. But then, a soft smile spread across your lips, and you reached out to take his hand in yours.

   "I had no idea," you admitted, your voice gentle and warm. "But I'm glad you told me. I feel the same way, Tanjiro."

   His heart skipped a beat at your words, and he couldn't believe what he was hearing. "Really?"

   "Yes, really," you confirmed, squeezing his hand reassuringly. "I've been drawn to you from the beginning, and I cherish every moment we spend together. You make my heart race, and I can't imagine my life without you."

   Tanjiro's face broke into a bright, genuine smile, and he felt a sense of euphoria wash over him. "I'm so happy to hear that, (Y/N). I promise I'll always protect you and cherish you with all my heart."

   You leaned in, closing the distance between you, and pressed a soft kiss against his lips. In that moment, all the pent-up emotions and longing they had kept hidden finally spilled over, and the connection between you deepened.

   From that night on, Tanjiro and you were no longer just friends and comrades; you became partners in love and life. The flame of your affection for each other burned brightly, and together, you faced whatever challenges came your way.

   As Tanjiro held you close, he knew that he had found something truly special—a love that was as enduring and fierce as the sun that rises every morning. And he vowed to treasure and protect that love for all eternity.
