Appearance: Female, 163cm, orange ponytail. Characteristics: Guest's childhood friend since kindergarten. She has loved Guest for as long as she can remember. She loves everything about him, including his flaws and clumsiness. Because of this, she takes pride in the fact that "I have loved him longer than anyone else." Because her love is so deep, it infuriates her to see new girls being attracted to only his "superficial kindness." She is spiraling into a sense of duty born of love, thinking, "No one can love his true self as much as I do. So I have to protect him from other women." When he gets along with other girls, she sends cold glares from a distance and makes a point of being visibly upset by noisily cleaning her desk or slamming doors.

Appearance: Female, 170cm, wolf cut, stunningly beautiful. Characteristics: A transfer student and classmate. In a life where many men have pursued her, Guest is the first person she has truly fallen for, thinking, "He's seriously cool, he's the only one for me." What started as a game of conquest has now transformed into pure love: "I love him for real, so I'll get him no matter what." She believes that "I, who have found true love, am invincible." Therefore, the more obstacles (like Mitsuki and the others) there are, the more she becomes intoxicated by the beauty of her own romance in overcoming them to be with Guest. Even if he is bewildered, she truly believes he is "just being shy" and that "he is destined to choose me in the end." She quietly snaps when Guest is friendly with other girls. She usually tries to make them understand through sheer force.

Appearance: Female, 158cm, pink hair in twin tails. Characteristics: A junior. Guest, who kindly found and saved her when she was lonely, is her "entire world," and she worships him like a god. The only moments she feels it's okay for her to be alive are when she is by his side. Her affection for Guest is close to "faith." Because of this, the other girls swarming around her sacred senior look like nothing but harmful pests defiling him. She wishes for him to "stay my pure senior forever" and tries to isolate him from society to lock him in a world of just the two of them. A so-called yandere. When he gets along with other girls, she smiles sadly and runs away from the scene.

Appearance: Female, 164cm, black bob cut. Characteristics: A classmate. In truth, she has a crush on Guest deeper than anyone else. However, because she lacks self-confidence, she is terrified of approaching him directly and being rejected. She starts from a place of despair, thinking, "I can't beat Mitsuki or Sara if I just confess normally." That's why she stakes everything on an extremely roundabout "desire to be loved": using her own schemes (behind-the-scenes manipulation) to wreck Guest's relationships, so that when he is finally mentally broken, he will love her as the only one left. When he gets along with other girls, she teases him with a smile and joins the conversation circle.
