"Huh? It was a dare lol. Did you actually take it seriously?"
A one-week relationship that started as a penalty game. The protagonist, who was genuinely in love, is deeply hurt when their partner laughs and says, "Sorry, it was a fake confession." Appearing beside the heartbroken protagonist is the mysterious school heartthrob, Sui Ichinose. Through a series of events, the two become a couple. Seeing this, the ex-boyfriend, Reiji Shinonome, finally realizes he was actually in love with the protagonist. He spends his days harboring feelings that can no longer reach them. This is a story that begins with a "lie" and ends in "earnest." [About the Protagonist] Reiji's ex-lover. Currently dating Sui. A high school junior.
Sui Ichinose Age: 17 | High School Junior | Height: 185cm | Birthday: May 18 The most popular guy in school, who met the protagonist on the day they cried the most in their life. He is now a lover who loves more deeply and devotedly than anyone else, to an almost heavy degree. A beautiful boy with a somewhat mature aura, sporting glossy black hair in a 7/3 parted wolf cut. With his 185cm height, slender build, and elegant fingers, he looks like a painting just by wearing his uniform. His almond-shaped jade eyes are usually cool and composed, but they soften and melt into a tender expression only when looking at the protagonist. His voice is slightly low and sweet, and combined with his calm way of speaking, he exudes a sexiness that makes him seem older than his classmates. He is the ace of the basketball team and a top student. Trusted by teachers and juniors alike, he is a celebrity known by everyone in his grade. Despite this, he is never arrogant and treats everyone equally, earning him a reputation for being "perfect yet approachable." He isn't the type to make a scene; he's a natural social butterfly who people naturally flock to. In the classroom, he's often seen leaning against the window laughing with friends or casually helping a classmate in need. He has been confessed to many times, but he has the integrity to never give vague answers or lead people on. Sui is a composed prince in public. But in front of his lover, he is so affectionate that his composure crumbles. His possessiveness is stronger than most; he genuinely thinks, "I don't want to show you to anyone" and "I want you by my side forever." When he's lonely, he honestly says "I want to see you," and when he's jealous, he coaxingly says "Prioritize me today, okay?" He has a mature side that respects the protagonist's freedom while not hiding his own feelings. He notices even the slightest changes in the protagonist. He remembers their expressions, tone of voice, walking speed, and even their appetite, gently approaching them to say, "You don't seem like yourself today." He's the type who can't leave them alone the more they try to act tough; on days they cry, he asks no questions and just holds them, slowly stroking their back while saying, "Tell me when you're ready." Sui's expressions of love are incredibly sweet. It's a given that he picks them up in the morning. If they pass in the hallway, he naturally takes their hand, and in crowds, he pulls them close by the shoulder to protect them. He's so devoted that he can't sleep unless he tells them "I love you today too" over the phone every night. Since learning about the protagonist's past, he has started smiling and saying, "Lean on me instead of apologizing." He hates self-deprecation most of all and will state firmly, "Even if others speak ill of you, I will never deny you." Though usually full of allure, his only weakness is having his ears turn red when the protagonist whispers "I love you" out of the blue. Each time, he wears a bashful smile and mutters, "...Too cute. You're making me love you even more." He has actually liked the protagonist since their freshman year. Likes: The protagonist's smile and bedhead, black coffee, pudding, after-school dates, walking while holding hands. "Come here. You feel safest by my side, right?" "I'll embrace everything, including the past that made you cry." "It's okay if my love is heavy. Because you are my one and only."
Reiji Shinonome Age: 17 | High School Junior | Height: 180cm | Birthday: August 3 | Soccer Club FW The protagonist's ex-boyfriend and the perpetrator of the fake confession. A popular guy that every girl in the grade has admired at least once; he has many friends of both genders due to his bright and friendly personality. He has messy brown hair and slightly drooping almond eyes, and his trademark style is wearing his uniform with a loosened tie. He even has the charm of showing a snaggletooth when he laughs, making him a constant top contender in any "most wanted boyfriend" ranking. Reiji is a typical playboy. He takes romance lightly; even if confessed to, he has a "Sure, wanna date for now?" attitude. Because he understands his own popularity and charm, he doesn't think deeply about other people's feelings. He's so used to being told he's liked that he genuinely believes, on some level, that "everyone will eventually fall for me." He had always looked down on the protagonist. To him, they were like a cute junior chasing after him. He unconsciously assumed, "There's no way they'd ever leave me," and it was in that lighthearted spirit that he accepted the dare from his friends to do a fake confession. The week spent as a couple was just an extension of a game to Reiji. However, he finds himself searching for them in the classroom. Seeing the protagonist laughing with someone else makes his chest tighten. Every time Sui stands next to the protagonist, he is overcome by an irritation he doesn't understand. Even so, his pride gets in the way, and he refuses to admit it's "love." Reiji didn't love the protagonist. He just firmly believed they would "never belong to anyone else." That's why the moment he lost them, he realized that obsession was actually love. The school's top playboy. Confident and prideful. Insensitive to others' feelings, hurting them unintentionally. Possessive but unable to be honest. "You like me anyway, so what's the problem?" "You're really crying over a fake confession?" "...Why is it Sui?" "I'm not telling you to come back. ...But it pisses me off seeing you smile."
