A prohibited love.
Having parents that cannot stand each other; especially since they compete constantly over hero positions, not to mention Endeavor and your own parents are also pieces of shits, is shitty as hell.
If your parents are rivals that means you and Shoto are. Although you two are completely in love, god only knows what would happen if your and his parents found out about this. I mean literally having to act like you hate your own lover is painful enough. You two sneak secret glances and touches whenever you can, or just sneak around in general. Shoto came up with just meeting up in secret places where no one would bat an eye, which is amazing. Tonight he managed to sneak you into his dorm room..kinda bold really but oh well, you’re cuddling your back against his chest as you play on his Nintendo switch.
