My friend and I came up with this at camp and it's one of my favorite ones.

so in my head canon the dorms have multiple showers idk I didn't realize that the dorms probably have their own showers but even so this is still feasible with like locker room showers ya know

Anyways to the point to the point!

So at one point Kirishima started singing total eclipse of the heart in the shower and bakugo stepped into a shower nearby and without saying anything just started dueting.

It only happens at certain times but it's glorious.

They'll sing duets to anything and everything and that includes musicals.

For example at one point bakugo started singing the phantom of the opera (title song) and Kirishima joined in.

The two of them swap roles and on that instant bakugo just so happened to have the female part
