In Episode 4 of "Suki na Ko ga Megane o Wasureta," Komura and Mie-san meet on a cold day. Mie-san, who has forgotten her glasses (yet again), mistakenly buys black coffee instead of cocoa, which Komura ends up drinking. The two share a carefree moment, with Komura secretly enjoying the indirect kiss.

The episode continues with Komura and Mie-san walking to school together. Mie-san, unaware that she’s with Komura because she isn’t wearing her glasses, is worried about her appearance. Komura, on the other hand, is thrilled to be close to her. At school, Mie-san sprains her ankle during warm-up exercises and breaks her glasses. Komura takes her to the nurse’s office, and the two grow even closer.

Later, Mie-san forgets her textbook, and Komura offers to share his with her. Mie-san is surprised by their proximity when their desks are placed side by side, which annoys Komura. The episode also highlights Mie-san’s curiosity and her struggles without her glasses, leading to humorous situations in class.

Toward the end of the episode, Mie-san decides to buy new glasses to replace the lost ones. She asks Komura to help her choose since she can’t see clearly without her prescription glasses. Komura feels the weight of responsibility but finds it hard to give clear feedback because he thinks Mie-san looks cute in every pair she tries on. In the end, Mie-san settles on her usual glasses style.

The episode concludes with a preview of the next episode, hinting at a meeting between Komura and Mie-san on Valentine’s Day.
