from what i've remeber, it started with the mc at a makeup popup ( he is like fixated on makeup), and he meets this girl (which is the other mc crossdressing) and later finds out he is his classmate so he gets closer with him anyways it rlly cute and fast forward the mc works at a makeup store

I hate the new wave of so-called ‘yaoi’ fans all because they cannot tell the apart of reality n fiction, they go out their way to harass an BL artist (syundei) just cuz of ‘problematic’ themes. If you find such things uncomfortable, nobody is forcing yall to continue it??? but instead you decided to bully off a nice artist who once enjoyed talking with her community, shame on those who think that was the “moral” thing to do especially those who like to ruin safe spaces all cuz it’s about dark subjects.
There is a new nickname for them now, 'puritans'.
