I'm not sure if it's natural because I had sex with her the last time we had a drink.... I'm not sure if it's natural or not. I'm relieved to hear that her boyfriend didn't find out about that time. He's also interested in me...? Isn't this a good chance...? (Oh, I'm not serious, it's just for fun (scum)). We went to Nacchan's house after listening to a lot of complaints.
