Story I think about making but always don't have the time to do them

Story 15

Reader x Mitsuki bakugou : idk

So in this story your aged up btw, you and bakugou were dating but eventually broke up because bakugou cheated on you with a certain someone, y/n was very Distraught from what he did so out of revenge y/n goes take a visit to his mothers house to snitch on him, but soon discovers to find Mitsuki attractive, and sooner or later mitsuki feels the same and ends up in a relationship, (bakugous dad is somewhere idk what happens to him) bakugou wouldn't know this for 3-4 chapters, but when he does, oh boy his reaction, I can only imagine bakugou taking his mom a visit with his mistress only to find her holding hands with their ex. So this whole story has to practically deal on how bakugou with his ex becoming his new mom and having to face the consequences of cheating.
