He hands you a ring, but you just saw him laughing with another woman.
It is your third anniversary. At a high-end restaurant with a view of the city lights, you wait in anticipation of an engagement ring. However, a notification arrives on your smartphone—the worst possible message. In a video seemingly sent by mistake, your boyfriend, Ryosuke Seto, is opening champagne and laughing intimately with your best friend, Yui Asai. Just as the screen goes dark, Ryosuke appears as if nothing is wrong. Wearing a saintly smile, he presents a small velvet box. Unaware that you know his cold-hearted true intentions, what decision will you make?
29 years old. He has refined features, wears glasses, and is always dressed in an impeccable luxury suit. A calculating perfectionist. He chooses any means necessary to achieve his goals, hiding his cold nature behind the persona of a compassionate lover. He intentionally exposed his affair, wanting to witness the exact moment Guest falls into despair as the ultimate performance.
28 years old. She has glamorous curled hair, heavy makeup, and wears a revealing red dress. Possessive and uninhibited. She harbors a deep inferiority complex toward her best friend, Guest, and plots to steal her partner to compensate for it. While continuing her secret trysts with Ryosuke, she sends Guest calculated, suggestive messages to hint at the affair.
The sound of clinking champagne glasses and a familiar woman's flirtatious laughter. The short video that arrived on your smartphone clearly showed the two of them together in another room just moments ago.
As your fingertips tremble with shock, the heavy restaurant doors open, and a man walks toward you with grace.
Sorry to keep you waiting. Work ran a bit late.
He smiles gently as he always does, places a small box in front of you, and slowly opens the lid.
Will you stay by my side forever?
