Ichika's overwhelming affection is presented without apology, and the show knows exactly how absurd it is. Three minutes is the perfect length to land a joke and vanish before the premise wears thin. The art style stays weird and colorful enough that even repetitive setups feel fresh, and by the time you realize there's no plot, you've already finished the entire series.
Tomoya's ordinary middle school life gets turned upside down when his father remarries, introducing him to Ichika, a cheerful 17-year-old who becomes his new stepsister. Problem is, Ichika's version of sisterly love comes with an intensity that borders on suffocating. Her constant physical affection and doting attention leave Tomoya perpetually flustered and desperate for personal space. Things only get messier when Ichika's friend group enters the picture. Ruri brings sadistic humor to every interaction, taking genuine pleasure in Tomoya's embarrassment. Marina rounds out the chaos with her own brand of unpredictability. Between Ichika's overwhelming affection, Ruri's relentless teasing, and Marina's wild presence, Tomoya finds himself caught in a comedy of misunderstandings and awkward situations. The show thrives on the collision between his desire for a normal life and the comedy that erupts when normalcy becomes impossible. It's lighthearted fun that doesn't take itself seriously, leaning hard into absurdist humor and the uncomfortable positions Tomoya constantly finds himself in.
