Use their eye color they're different so you'll know
I tried, believe me, but since their heigths vary all the time I was even more confused, the only ones I could recognize were the mc, lover boy and mole boy (+ the girl since there's no-one to confuse her with)
Ok~eye color and characters:
The blue eye: character that dated his dead brother
The brown eye : replacement of the dead brother aka the blue eye "boyfriend"
The grey eye: the one that does the dirty work for the reading club
The gold eye: the one that is dating the main character
The green eye: the girl
The glasses boy: the one that listen to the gold eye boy
Thank youuu
Pleasure
Seriously, can there be improvement in the character design? I almost don't recognize anyone （/TДT)/
