I'm a timid guy who gets beaten up and beaten up by the locals all year round, but recently I got a super cute and serious girlfriend at university. Her name is Yuri-chan, she came from a girls' school outside the prefecture, she's a really serious girl who's good at cooking... But the other day, while I was enjoying a healthy, lovey-dovey relationship with her, the most charismatic delinquent in the prefecture, "Takemaru-senpai," suddenly showed up, saying he was there to collect the proceeds from the party tickets...!
