The Quirk Marriage (Todoroki x Reader)

The Todoroki's and the {L/N}'s have always been close, both living in the limelight. When the youngest children of the two families, {L/N, Y/N} and Todoroki Shoto, develop strong quirks, they are pushed into a Quirk Marriage, one they can't escape from. Due to this, they have to act like a happy couple in front of the media and their parents, although they secretly despise each other.

What will happen when they both are accepted into UA, and end up in the same class?

Can they fix their relationship?

Or will they spend the rest of their lives hating each other?

~Note~ I own none of these characters (: They all (apart from {Y/N}) belong to Kōhei Horikoshi.
Also, the cover art is not mine. I found the picture on google :<
