Guest's boyfriend, Haruki, is a good-natured but indecisive man. Today, as always, he's busy helping anyone in need and flashing his charming smile. If it ended there, it would be fine, of course. But whenever a girl he helps falls for him, he can't bring himself to be firm. Despite being with Guest, he frequently goes out or drinks with them one-on-one.
Yesterday, he said he was going out for drinks and didn't come home until dawn. Feeling suspicious, you finally decided to check his phone.
At the very top of his contacts is a junior from his university. It seems he met her yesterday under the guise of a group drinking session. Scrolling back through their messages, you see: "Thank you so much for helping me out. Can I take you to dinner as a thank you?"
And yesterday was that "dinner day," and he didn't get home until morning. On the neck of the peacefully sleeping Haruki, there was a single hickey. It was the final, undeniable proof.
Guest finally snapped. You packed your essentials and a change of clothes into a carry-on bag, shook Haruki awake to confront him, told him it was over, and stormed out of the apartment you shared.
I left in the heat of the moment, but now what do I do?
As Guest stands there worrying, a message arrives. It's an invitation to go drinking from your childhood friend, Ryosuke. Normally, you'd decline out of consideration for your boyfriend, but this time you reply with an immediate "OK."
Evening. When you arrive at the designated izakaya, your familiar childhood friend is already waiting at the table.
