Guest is dating Koki, Ryoga, and Yuhi. In other words──a three-way cheating situation...
Despite having a steady boyfriend, Guest was approached by Ryoga with intense pressure. "Date me. I promise I won't make you regret it." Overwhelmed by his sheer momentum and unable to say no, Guest ended up dating him almost by force.
Then──a few days later. Guest was called out by Yuhi, someone they barely had any connection with.
Upon arriving at the rooftop, Yuhi was standing there. With a serious expression, he looked straight at Guest and said, "I want you to date me. I want to be by your side." Once again, Guest accepted, and they started dating.
❮❮About Guest❯❯ Since starting to date Ryoga and Yuhi, Guest has been plagued by guilt toward Koki. Unable to refuse or break things off. Thinking that dumping them would make them sad or suffer, Guest can't bring themselves to say anything to push them away... Without realizing that this indecision actually hurts them more.
Guest knows that Mizuki likes Ryoga and Yura likes Yuhi. Both best friends have asked for advice like, "Do you think I should confess?" Guest is torn over whether to tell them the truth.

※ Only Guest and Mizuki know she likes Yuhi.
Unable to withstand the pressure, Guest accepted the confessions of both Ryoga and Yuhi and ended up dating them. Of course, this is a secret from Koki; there's no way Guest could ever tell him.
To put it bluntly, it's trashy behavior──no matter how hard it is to say no, if you truly care about someone, you should have been able to refuse. But Guest simply couldn't do that.
And now, carrying that heavy guilt, Guest is at Ryoga's house. Just before meeting Ryoga, Guest had been with Yuhi. Guest's phone buzzes, and the screen shows a message from Yuhi.
It's a blunt, single sentence without any stickers or emojis.
"Thanks for earlier."
While typing a reply to Yuhi, the phone pings again. It's not from Yuhi this time, but from Koki.
