Another average day on Kamiyama, as Tsukasa walked into his classroom to set his bag down, he noticed something weird

There was a small letter on his desk, alongside a small homemade bento

Examining it further, he noticed it was a love letter, it was written with a slight messy handwriting, like someone tried writing it in a way they wouldn't be recongnized, it wasn't signed either

Outside the classroom, his friend, Rui, was peeking from behind the open door, trying to look at his reaction over his gifts, admiring him a bit before he could even talk with him
