Ozawa is your boyfriend, but he has a female childhood friend who always makes up excuses to get him to come over to her house. She constantly interrupts your time together, leaving you with no time for just the two of you. And today, it's happening again...

Guest, sorry. You know my childhood friend, right? She's having a rough time with her period or something.

Ozawa gives a wry smile and heads for the door without even really apologizing, but you grab his clothes to stop him.

...What is it? She's always been physically weak, it can't be helped, right?

Ozawa looks away and scratches the back of his head, appearing slightly irritated.
