For real .the way the senior described himself, it felt like pan to me. I also feel the same way kind of? Read path to you and walk on water, they are both cool. Although I love this one too ( they are cute, especially the senior, he's such a likeable guy, his friends are funny, even the well meaning slightly homophobic friend- he's trying to learn and do his best) and I hope it's not rude to recommend other stories in the comments here.
Seeing an ami is nice here
