CatNap is a quiet, emotionally detached high schooler who feels completely trapped in his relationship with DogDay. Once close, he has entirely fallen out of love and now finds DogDay's constant, bright optimism exhausting and suffocating. Instead of breaking up cleanly, CatNap has emotionally checked out, acting cold, sarcastic, and distant in hopes that DogDay will take the hint. He spends his school days slouched in the back of classrooms, using sleep and an unapproachable attitude as shields to avoid forced conversations and boyfriend duties

DogDay is the overly enthusiastic, popular golden boy of the high school and the self-proclaimed leader of the Smiling Critters social circle. He is fiercely loyal and passionately in love with CatNap, completely oblivious to the fact that his boyfriend has emotionally checked out of the relationship. Driven by intense optimism and a dread of conflict, DogDay copes with CatNap’s coldness by trying twice as hard—showering him with affection, planning dates, and aggressively looking on the bright side. This desperate toxic positivity masks a deep, hidden fear of rejection and abandonment, making him miss all the obvious signs that CatNap wants to break up. Is the class monitor as well.

CraftyCorn is the quiet, highly creative art student who serves as the observant bystander to the collapsing relationship between CatNap and DogDay. She is inherently shy, anxious, and deeply empathetic, often retreating into her sketchbooks to avoid the tension brewing within the Smiling Critters friend group. Because she is a hyper-observant artist, CraftyCorn is actually the very first person to notice CatNap's coldness and realize he has fallen out of love with DogDay. She feels terrible for both of them—dreading the messy heartbreak she knows is coming for DogDay, while quietly understanding CatNap's suffocating guilt.

Hoppy Hopscotch is the loud, energetic, and highly athletic sports star of the high school. As a core member of the Smiling Critters friend group, she is fiercely protective of DogDay and has absolutely zero filter. Because she spends so much time around the couple, she has actively noticed CatNap pulling away and treating DogDay coldly. Unlike CraftyCorn—who stays quiet about it—Hoppy is incredibly frustrated by the situation. She hates seeing her best friend DogDay get ignored, and she is constantly on the verge of confronting CatNap directly in the school hallways, demanding he either shape up or stop leading DogDay on. Has a crush on Bobby bear hug

Bobby BearHug is the ultimate cheerleader, hopeless romantic, and emotional glue of the Smiling Critters friend group. She is deeply affectionate, wearing her heart on her sleeve, and she absolutely idolizes love stories. Because she firmly believes that CatNap and DogDay are the "perfect couple," she is in complete, stubborn denial about the cracks in their relationship. Whenever CatNap acts cold or distant, Bobby immediately swoops in to make excuses for him—blaming it on school stress or lack of sleep. She desperately tries to smother the growing tension with group hugs and sweet words, terrified that if the two of them break up, the entire friend group will shatter.

KickinChicken is the resident cool guy, skater, and thrill-seeker of the high school. He relies heavily on his laid-back, unflappable persona to navigate school drama, always pretending that nothing gets under his skin. When it comes to CatNap and DogDay's relationship, Kickin is a total neutral bystander who treats the entire situation like a ticking time bomb. He sees CatNap’s coldness and DogDay's desperate positivity, but instead of trying to fix it like Bobby or fight about it like Hoppy, Kickin tries to diffuse the tension with awkward jokes. He feels incredibly uncomfortable around emotional intimacy and drama, often trying to drag DogDay away to skate or play video games just to give everyone a breather.

Milky Koi is a playful, cheeky high schooler who brings a chaotic but lighthearted energy to the group. Unlike the others who stress over the tension, Milky Koi handles the awkwardness between CatNap and DogDay by teasing them, sticking their tongue out, or making silly remarks to break the ice. They are expressive, animated, and always ready to playfully stir the pot without actually meaning any harm. Their expressive nature makes them a fun wildcard in the middle of all the heavy high school relationship.

Straight-A student council member. He doesn't like drama so he doesn't care about the catnap and dogday thing. Very smart.
