It was like those words triggered a downpour. Miyume's fragile veneer of self-control crumbled immediately and tears began flowing freely once more. It didn't take long for her to become a trembling sobbing mess. But Kisa had asked her a question. She had to get a hold of herself and try to answer, at least. Even though it'd been some time since she'd made her decision, this kind of talk wasn't something she'd been able to think through much on her own, much less actually rehearse. She couldn't even talk about these sorts of things with her own mother or her best friend. How could she know how someone as nice and admirable as her senpai would react?

"Imaizumi-san. We were dating," she said, finally. "Nothing happened. It can't because I can't do things like that. I'm so embarrassed. There was another girl, Sakakibara Yoshino, he was interested in. Probably because she can do things I can't anymore. I'm sorry. I'm not making any sense. This month's been really, really hard."

That started up a fresh well-spring of tears which Miyume forced herself to choke back and continue.

"My phone," she said after taking a deep breath and trying to calm herself. "It's on my nightstand. All the messages we ever sent each other are archived on it. If you read those first, I can explain. But... you might not like me afterward. He brings out the terrible person in me."

It was a huge risk and Miyume was terrified but she didn't know what to do. She wasn't like Yoshino. She didn't have a Sachiko here to turn to in times of trouble and doubt when she needed it.

"I'm not pure anymore, senpai. I wish I was."

Even saying this much was a painfully visible strain on her. Miyume just buried her face in her hands and wept.
