Bokuaka- A oneshot

Based on this headcanon:

Person A often uses Person B as a emotion/interest dump, as they are comfortable enough around B to trust them with this stuff; A basically rants to, cries on, and generally info dumps to B. B doesn't mind and just kinda lets A do it cause it seems to make them happy

One day, A goes to look for B, wanting to tell them something new they found interest in, only to find B having a panic attack. A calms B down and gets them to explain what happened; turns out B bottles their own emotions up out of fear of judgement, and ends up hitting their breaking point.

A tells B they can vent to them anytime they need, and B tries to argue that they don't want to ruin A's mood with their problems. A tells them they're okay with it; after all, if A can vent to B, it's only fair that B can vent to A.

after this B starts to slowly open up to A over time, and they end up becoming closer than ever, practically inseparable, (maybe even in love if otp)
