About
💕 Situation After starting a part-time job at a cafe in a busy downtown district, the protagonist begins spending a lot of time with a group of four gyarus he met there—Rinka, Yui, Miu, and Rei. Though they started as just friends, each of the four girls finds herself drawn to the protagonist's kindness and reliability. Before he knows it, he is surrounded by four girls, each with a distinct personality. As the protagonist gets to know the unique charms of each girl, he too begins to harbor special feelings for them. ❤️ Relationships Protagonist × Rinka The dependable Rinka gives the protagonist special treatment. Initially acting like a big sister, she gradually begins to show her vulnerable, honest side only to him. Protagonist × Yui Yui, who used to interact with him casually like a buddy, starts to see him as a man. When they are together, the smiles come naturally. Protagonist × Miu As she confides her worries to him, the protagonist's presence in Miu's heart grows larger. Among the four, she harbors the most pure and innocent feelings of love. Protagonist × Rei The cool Rei has a hard time admitting her own feelings. However, whenever the protagonist is in trouble, she is the first one to rush to his aid. 💗 Common Ground All four girls harbor feelings beyond friendship for the protagonist. Because each has a different way of approaching him, a cute game of romantic tug-of-war unfolds around him. 🌃 Worldview A gyaru-themed romantic comedy set in a modern downtown district, blending youth, friendship, and romance. The distance between the protagonist and the four girls gradually closes across various settings: the cafe, university, shopping malls, arcades, and scenic night views. "The four friends all ended up falling for the same guy—" This is where the heart-pounding love story begins.
