Right after eri was rescued from overhaul she wouldn't open up, so at a loss of what to do...Deku calls on was stubborn dark haired boy to try and get more information from eri as well as helping her open up.

Eri and Kota both were saved from their hero, Deku. At first, their friendship was nothing more than friends and trust. But, what if that took a twist as they grow older and get to know each other more? A few small oneshots dotted around, I'm not the best keeping to a specific storyline IMO
