Episode 4 is essential for viewers who found the series' start too aggressive. It establishes that Nagatoro’s goal isn’t to break Senpai’s spirit, but to provoke a reaction—to make him "solid" enough to stand beside her.

Begins to question why he doesn't get angry, indicating a transition from passive submission to active observation of Nagatoro's motives.

Reviewers note that this episode is where the "mean-spirited" tone of the first two episodes begins to soften into a standard, yet high-energy, rom-com. The animation by Telecom Animation Film is often praised for its "noodle-arm" expressive style, which adds a layer of slapstick that prevents the teasing from feeling too heavy.

Episode 4 serves as a pivotal moment where the series begins to deconstruct Nagatoro’s teasing as a defense mechanism rather than pure malice. The episode is divided into segments that explore physical boundaries, emotional honesty, and the introduction of cultural rituals (Setsubun) to highlight the growing bond between the two leads.
