Koukando ga Agaranai

Rikka, the only daughter of a wealthy merchant, leads a quiet life until her father brings home a sullen young boy. Confused by his distrustful demeanor, she is startled when a pop-up screen appears, displaying his name, age, favorite food, and other details. This triggers her memories of a past life, where she recalls this world as one from an otome game her younger sister used to play. The screen also reveals that the boy has an unusually negative affinity rating of minus 30 toward her.
