Fake dating

Kirishima asks Kaminari if they could pretend to be dating to making a certain blond-haired boy jealous. Being the bro that he is, he accepts instantly.
But what happens when Kaminari realises someone likes him and he likes them back, but his fake relationship is bringing them further and further apart? Also, is Kirishima making the right decision? Or is he going too far for his crush to like him back that he ends up hurting them emotionally?

Lots of fluff.
Very very very veeeeeery small amount of angst.

This is yaoi (boyxboy) so if you don't like it, don't read this.
