Chapter One (Revised)

This story is going to under some major renovation due to poor writing, lack of consideration for multiple genders, and becuase it does need some major editing. Thank you, and please be patient with me.
Two pro heroes, who graduated in the same class, are now teaching at Yuuei(U.A.). Their romantic feelings towards one another is not a mystery, but will the torment of (Y/n)'s past prove too much an obstacle for the two?
