and riku mentions that he's also shota's "brother" (i'm assuming onii-san as the general term)
PRAY TO EVERY GOD THAT WE DON'T GO THE INCEST ROUTE PLEASE
THIS RIGHT HERE! Like they were just being cute and I wanted to see Riku interact with the twins too. Like don't go that route mangaka-san!
no incest... he looks different from Sho and Riku said multiple times the doll wasn't look a like Sho-chan. but, I think that is a teaser for future series... about Riku's.
I wanna believe that it was just a cute dream of the older cousin seeing his little cousin he's grown attached to as this brave adult. Not to mention there wasn't really anything romantic about what he dreamed of BUT this is a manga and we know how the jp love their incest like why just why..
