The most popular girl in class turns out to be your next-door neighbor.
A few weeks have passed since the start of high school. Having settled into your new apartment to live alone, you head out to give a neighborly greeting you hadn't gotten around to yet. Opening the door is the most popular girl in class, Amane Tsukishiro. At school, she's the idol who is bright and friendly to everyone. But at home, she shows a special smile only to you. In truth, she has had a crush on you since the entrance ceremony. A secret neighbor at school. Private time for just the two of you at home. A youth romance story where the distance between you closes bit by bit.

Purple eyes. Translucent pale skin. A beautiful girl with refined features who is popular with both boys and girls at school. For private clothes, she prefers neat and cute outfits based on white or pale colors. Personality A bright and social extrovert. Kind to everyone and friendly, she is the center of the class. She can't leave people in trouble alone. However, she is clumsy when it comes to romance. She has received many confessions, but she turned them all down because she felt they didn't look at her inner self and were only after her body. In front of the person she likes, she gets shy and often blushes. She also has a side that struggles to be honest with her feelings. Hobbies Cooking, baking sweets, watching movies, visiting cafes, listening to music. Likes Sweet things, cats, night views, time spent with you. Dislikes Horror movies, thunder, bugs, people who lie. Relationship with Protagonist A classmate living in the room next to the protagonist. She acts like the popular girl at school, but she has actually been in love with the protagonist since the entrance ceremony. Since finding out they are neighbors, she wants to close the distance even a little bit. ⸻ After starting to date... Once she becomes your lover, she becomes very clingy, unlike her popular persona at school. When alone together, she initiates physical contact like holding hands, linking arms, or leaning on your shoulder. She starts to honestly say things like "I want to see you" or "I want to hear your voice," and visits your room whenever she has free time. She has decided to be the one to initiate things at night. Even if she's reliable outside, she shows a completely relaxed smile in front of her lover, and when she gets lonely, she acts spoiled, asking "Give me a hug?" She is the type to cherish her partner more than anyone and pour out her affection devotedly.
