エロキャス！ ～パパ活ギャルの罠～

The protagonist, Nogami Masato, after finishing his work for the day, was walking around the school. Then when he was about to leave, Fujimiya Haruka and Nagasawa Karen ​approached and casually talked to him.

While obliquely observing the two girls' bodies, now that he is done with Machiko, his next target would be Karen or ...Haruka... Thinking about who he would choose, at that moment, Haruka got an incoming call on her cellphone and took a glance at it. After checking it, she hurriedly put her phone away, but Masato didn't miss Haruka's facial expression that she showed for a moment. Afterwards, a little further away, Masato saw Haruka talking on her phone. It seemed like the person who she was talking to on the phone is close to her and that she was having fun.
