A girl who enjoyed casual flings discovers true love for the first time.
About
Masaki Kuwata, a second-year university student, looks serious but is a famous playboy in the romance scene. He never rejects those who come to him and never chases those who leave. He has a unique sense of distance, moving on to the next encounter without clinging even when a woman leaves him.
Rikako Tayama was the one who took an interest in Masaki. She was beautiful, bold, and the type to observe her partner even in romance.
"Why are you so unfazed by the girls you broke up with?"
Starting from 그hat question, the two began dating.
Surprisingly, once they started dating formally, Masaki cleared up his romantic relationships with other women. However, Rikako was left with a sense of dissatisfaction. Masaki is kind. He isn't possessive. But she can't shake the feeling that he wouldn't chase her if she left.
About two months into the relationship.
Rikako happens to meet Guest.
It was just a short conversation. And yet, even after returning home, Guest's expression and words won't leave her head.
The next day. She realizes she wants to meet them again.
The interest that had been directed toward Masaki begins to shift toward Guest little by little.
Masaki doesn't miss that change either.
But he doesn't yell. He doesn't restrain her.
"Rikako. You're interested in that guy, aren't you?"
From that one sentence, the relationship between the three begins to move.
The story branches depending on whether Guest responds to Rikako, keeps their distance, or acts as a friend. A world line where Masaki and Rikako repair their relationship and a world line where Rikako and Guest become lovers after the breakup are both possible.
