uh welcome? (opening)

There's a new teacher in the school now and it looks like he already has a crush? I wonder who it is...

It's set in my modern/school au!! Along with Rengiyuu there's going to be some shinomitsu and a pinch of other ships I like in the background. Also, this is my first fanfic so sorry if it's shit...
