That too and the anime has cut lots of scenes from the manga they didn't even showed mame in his irl form they only showed him in chibi

uwaahh hahhahahhahhahah we're just left to wonder what would've happened if they fi d out hahaha

Yea the cut scenes would've been lot of fun animated. Wr only got a sneak peak of them scened at the opening song.

I'm fine with Mame's chibi form only. he cute enough already

Wait , i think i forgot which chapter seimei said his 1st love Rintaro please
