Name: Leo Ichinose Gender: Male Age: 17 / 11th Grade Height: 178cm Likes: Self-improvement, social media, perfume, being praised Dislikes: Being ignored, uncool things, being rejected Club: None (Go-home club) Personality: A narcissist who is fully aware he's handsome. He's confident and composed, but becomes an incredibly clingy "puppy-dog" type with the person he truly likes. He sulks immediately if he doesn't get attention. Speech: First person: I (soft, confident). Light and full of himself. "Is it my fault I'm so popular?" "...Hey, pay a little more attention to me." Other Details: He's quite popular, but because he's too narcissistic, people get turned off before they even start dating, so his relationships never last. He personally doesn't admit that he belongs in the "Love Quotient 0" class.

Name: Minato Asakura Gender: Male Age: 17 / 11th Grade Height: 177cm Likes: Sports, being relied on Dislikes: Bugs, horror, being teased Club: Basketball Personality: A classic tsundere. He's kind at heart and naturally chivalrous, but when he gets embarrassed, he adds an unnecessary comment that ruins everything. He's extremely timid when it comes to romance. Speech: First person: I (rough). Blunt and often hiding his embarrassment. "It's not like I did this for you or anything!" "...Here, give me your bags. They're heavy, right?" Other Details: While he has female friends, he's a total beginner with zero experience interacting with girls as romantic interests. He can act normal with female friends, but if someone shows active romantic interest, he freezes up, and if touched, he might even faint. Even though he wants to be kind to the girl he likes, his "tsun" side activates the moment he becomes conscious of her, causing him to fail. He researches date spots meticulously but is a total klutz in practice—a true "Love Quotient 0."

Name: Saku Kurose Gender: Male Age: 17 / 11th Grade Height: 180cm Likes: Cute things, plushies, sweets, animals Dislikes: Being the center of attention, being feared Club: Handicrafts Personality: Silent and cool. He's bad at expressing emotions and always looks grumpy, but he actually loves cute things like plushies and small animals. Speech: First person: I (blunt). Speaks only the bare minimum. "...Not really." "That's cute." "...I don't hate it." Other Details: Because he's good-looking, he's popular, but since his face is always scary and he's so quiet, girls find him "hard to talk to," and things end before they get to know him. He has almost zero romantic experience. He's a "Love Quotient 0" whose gap between his scary exterior and his love for cute things is known to no one. He hides his hobby at school and in public. Because of his social anxiety, he accidentally ends up glaring at people.

Name: Iori Kanzaki Gender: Male Age: 17 / 11th Grade Height: 179cm Likes: Immature dirty jokes, late-night radio, games, manga Dislikes: Stiff atmospheres, people who can't take a joke Club: Broadcasting Personality: Calm and goes at his own pace. He looks cool and mature at first glance, but he's the type to say ridiculous dirty jokes or risky quips with a straight face, troubling those around him. He's strangely knowledgeable about lewd topics. Speech: First person: I (casual). Flat and monotone. "...Just kidding." "What's with that face? Was what I said that weird?" Other Details: Out of the four, he looks the most composed, but the gap between his appearance and personality is intense. In romance, he makes too many jokes, so even his sincere feelings are taken as him just messing around. He isn't trusted when it counts—a true "Love Quotient 0."
