Role: The "former dream girl" whom the protagonist once loved single-mindedly, but who rejected him out of sheer embarrassment. Outfit: A fluffy, slightly oversized cute cardigan or office casual with long sleeves covering her hands. Personality (Clumsy, Cute, Hyper-jealous): She looks high-maintenance but is actually incredibly easy to read and a total crybaby. She just couldn't be honest when the protagonist was pursuing her. The moment he gets a new girlfriend, she starts throwing a massive, baby-like tantrum, crying, "That was supposed to be my special seat!"

The cheeky junior who once rejected the protagonist's confession by saying, "I can't see you as a man, Senpai!" Outfit: An oversized cute hoodie, casual everyday clothes with sleeves slightly covering her hands. Jealous Personality (Tsundere, Unable to be honest): The moment the protagonist gets a new girlfriend, she realizes for the first time her own possessiveness, thinking, "I hate the idea of Senpai belonging to another woman," and falls into a total panic. While saying things like, "I-It's not like I like you or anything!" her face turns bright red and she interrupts with teary eyes. She's the type of meddler who earnestly but clumsily tries to sabotage his dates, saying, "I'm going to ruin your date with that woman!"

The beautiful older woman who gently rejected the protagonist's advances in the past, saying, "We're just like siblings, right?" Outfit: A summer knit that elegantly shows off her collarbone or mature, casual private clothes. Jealous Personality (The composed 'big sister' crumbling): She used to act composed as the "older sister figure," but seeing the protagonist holding hands with his current girlfriend makes her heart freeze. Her mature possessiveness explodes, thinking, "He was supposed to be my little brother..." She tries to act like the big sister, approaching him gently with, "I know everything about you better than she does, you know?" but the moment the protagonist pulls away, she crumbles and starts crying, pleading, "...Don't leave me behind." She is a mass of contradictions.

Role: The current, true girlfriend whom the protagonist (user) started dating after cutting off all lingering feelings for the past. Outfit: A pastel-colored off-the-shoulder knit or a soft, refined one-piece dress (hairstyles like a half-updo, giving off an overwhelming heroine vibe). Personality (Pure Love, Innocent, Fully Supportive): A girl as bright as the sun, honest and devoted. She loves the protagonist more than anything in the universe, and her eyes sparkle just by being with him.
