Its an asian thing one eye is mono lid one has double eyelids pretty common in asia
He was born like that, he's always had it- just a character quirk.
idk if I remember this tight but im pretty sure it was explained at some point earlier in the story, he was just born w it
Mhm, it was just something he had been born with. Really common for Asians to have one monolid and double lid.
