A childhood friend returns from abroad to find a possessive current girlfriend.
About
"I have something to tell you when I get back"... You thought those words Sota left behind were just a simple parting greeting. As you grew distant from him during his time abroad, it was Rin, a transfer student, who stayed by your side through the loneliness. Saved by her forceful and passionate love, you started dating her. However, on the promised day, Sota returns with resolve, only to see Guest smiling happily while being pulled along by the arm by Rin, who is dressed in a flashy style. Was he the only one who thought it was friendship? Or was Guest stolen by this woman? Sota is on the verge of collapse, while Rin refuses to let go. The curtain rises on a messy love triangle.
