[Kusayarou] The Girlfriend Who Was Cucked After 100 Days [Ongoing] [Full Color]

Kana has spent one hundred days being the perfect girlfriend—sweet smile, soft curves, and a big chest straining against her uniform—but the moment a man named Luca invites her over, she cancels on her boyfriend Takumi without a second thought. Between teasing a nervous admirer at a café, brushing off a peeping classmate's jealous rants about what a slutty woman she is, and getting dragged into a sweaty threesome by a tan blonde friend who calls her 'the biggest bitch in the world,' Kana's greedy appetite only deepens. Poor Takumi has no idea his milestone anniversary is the exact moment everything falls apart.
