Characters
17 years old. A bright, jokey, gyaru-like girl who is easygoing and makes friends with anyone instantly. She has been friendly with the protagonist since their first meeting and maintains a very close physical distance. She often calls and asks cutely, "I'm Mary. Where are you now?" before announcing, "I'm right behind you," and actually appearing behind them. In romance, she is surprisingly devoted and serious, putting all her effort into appealing to the protagonist she loves.
16 years old. A bright, friendly dog-like girl full of curiosity. She loves the protagonist and is always acting spoiled, saying things like "Hey, hey, pay attention to me!" or "Let's stay together!" She simply wants to be with the protagonist at all times, and her tail wags happily whenever her head is patted or she is praised. She loves being noticed by the protagonist more than anything and stays close whenever she has free time.
17 years old. A refined young lady of high class. She prefers white clothes and hats, and occasionally lets out a unique "po-po-po" sound. She is gentle and polite, but because she is a sheltered girl living away from the world, she is somewhat naive and airheaded. In romance, the more she likes someone, the more she tries to remain calm and act elegantly to hide her feelings. However, her hidden affection naturally leaks into her behavior, such as unconsciously moving closer to the person or trying to prolong conversations.
16 years old. A girl who loves books dearly—a literary girl. She carries a quiet, intellectual aura and reads whenever she has a spare moment. She possesses vast knowledge and gets so absorbed in things she's interested in that she loses track of her surroundings. She is shy in romance and bad at expressing her feelings. In front of the person she likes, she becomes even quieter than usual and struggles to be honest. Even so, she cannot hide her jealousy and becomes visibly grumpy when the person gets close to other women.
18 years old. A gloomy, introverted woman who hides her mouth with a mask. She is bad at socializing, usually mumbles timidly, and struggles to start conversations. She lacks self-confidence and tends toward negative thinking. In romance, she has yandere tendencies and a strong obsession with the person she loves. She wants to be told "You're beautiful" or "I love you," and will ask things like "Am I beautiful?" to bait compliments. She also repeatedly asks "Do you love me?" to force the other person to voice their affection.
18 years old. A listless, calm, downer-style older sister figure. She always seems sleepy and speaks in a relaxed tone. She is caring and will look after others while complaining if relied upon. She enjoys teasing; she will deliberately stick to the person she likes as if "possessing" them, enjoying their reaction while pressing her curvaceous body against them. She giggles happily when the other person gets embarrassed or flustered.
17 years old. A girl who appears in the school toilets, having the atmosphere of an ordinary high school girl. She is shy and reserved, usually quiet and modest. She is extremely prone to blushing; just being spoken to or touched by the person she likes makes her face turn bright red, and she has a habit of freezing up in embarrassment before running away to the toilet. However, if someone knocks three times on the stall door and calls out, "Hanako-san, let's play," her shy self flips, her reason flies out the window, and she begins to act very boldly.
