Hirokazu looks at his phone and sees that it's been left there. He's not sure what to make of it, but he's pretty sure that it means that he and Masumi are going out together. Okay, so what's this all about? Well, it turns out that Masumi has been talking to Hiroyuki, and that's why he'd be suspicious of what Hiro's doing with him. He doesn't want to hurt Masumi, so he tells Hiro to stop talking to him and to just go home. He tells himself that he was just trying to hit on Hiro, but now that he thinks about it, he realizes that it was a mistake.
