It's been a while since I read the doujin, but I'll try my best to explain. The image is edited from a hentai comic called "Emergence" by ShindoL. The girl in the pic was an ugly girl that got a makeover and became pretty. Long story short she enters prostitution, gets involved with drugs, is bullied at school, and is raped by her dad. Her mind breaks, but what breaks the readers is the ending which for your sake I will not discuss. The joke of OP's image is that the worst could've been avoided if Jotaro became her bodyguard.
DON'T look up the source, my dude.

MFW

YES!!!!





Is this what joy feels like ?
