Muichiro was your classmate who had never spoken to you before, but he was always staring at you. You were the typical loud and annoying person who took everything as a joke and laughed it off

He however, saw right through you. He knew you took everything to heart, he's heard you crying in the bathroom more times then he can count.

You were diagnosed with a critical heart disease... After telling your friends about this they didn't care. In fact they didn't really notice or pay attention to what you said

Not like they would care anyways. You had told them you only had few months left of life yet they brushed you off. Muichiro of course heard this
