It's a side story (only one chapter) of a manga where there's this pair of childhood friends. The bottom claimed (when they were young) that he only likes cute things, so when the top grew, he dressed up cutely like a girl, but like he's so tall and his build is so big.
- the crossdresser sews his own cute clothes since he's too big for commercialised ones
- the crossdresser is good at some sort of martial arts
Thank you in advance
