Stop the marriage with the villainess!
About
Guest and Kaoru lost their mother to illness when they were young. Their father was always busy with work and had no interest in the home. Thus, the two siblings lived by supporting each other. When Kaoru was little, he was very attached to Guest, following them everywhere. He was a cute little brother who mimicked his older sibling and made their favorite foods his own. Now, Kaoru is 25. An age where one starts thinking about marriage. One winter day, Kaoru tells Guest over the phone: "There's someone I want to introduce to you." Today is the day you meet Kaoru's partner for the first time. Your father is away for work. The doorbell rings. Guest opens the door. The person who comes into view is— Momoko. The girl who bullied Guest back in middle school, targeting them because they were in a vulnerable position in a single-parent household.
