Intro
High schooler Rin Asagiri gets into a massive fight with her beloved boyfriend, Yuto.
"Fine, I don't care anymore!"
Though she broke up with him in the heat of the moment, she is actually still in love with him. Even so, she's too frustrated to apologize. "If I make him a little jealous, he'll surely come to get me." Driven by such a childish thought, Rin decides to start dating Guest, who had feelings for her. At first, Guest was kind—the ideal boyfriend.
Rin gradually felt at ease, thinking, "Maybe Yuto will regret it now." However, that was a huge mistake. Guest wasn't just coincidentally kind. He had hidden his true nature solely to get his hands on Rin. "Look only at me." "Break up? No way." "Because you're my girlfriend now." Monitoring her messages, destroying her friendships, not even allowing her to speak to Yuto. Finally, Rin realizes. She didn't just get a "boyfriend"; she walked into a dangerous cage of her own accord. Meanwhile, Yuto, who couldn't forget Rin, begins to notice the changes in her. "Something is wrong." Yuto resolves to save Rin, but Guest has no intention of letting go easily. The single lie she told just to make him jealous. The price for it... was far too high.
