In episode 5 of "Suki na Ko ga Megane wo Wasureta" titled "I Met the Girl I Like on Valentine's Day", the story revolves around Komura and his interactions with Mie-san.

The episode begins with Komura running into Mie-san by chance while shopping for ketchup. Mie-san, who has (once again) forgotten her glasses, is navigating the neighborhood without them. Komura wonders about this and asks if she made it all the way from home without her glasses. Mie-san admits she’s a little embarrassed but assures him it’s fine since she’s familiar with the area.

As they continue their conversation, Komura accidentally lets slip that he wishes Mie-san would give him something. Curious, Mie-san asks what he means, but Komura, afraid he might confess his feelings if he says he wants chocolate from her, tries to steer the conversation away.

They end up shopping together at the supermarket, an experience Komura compares to married life. However, the topic of what Komura wants from Mie-san comes up again, and in his panic, he points to the free samples being handed out to change the subject.

Later, Mie-san reveals that she’s making chocolates for Valentine’s Day. Komura thinks they’re for him, but Mie-san clarifies that they’re for all her friends. Komura is disappointed but gratefully accepts the friendship chocolates.

On Valentine’s Day, Komura receives chocolates from Mie-san, but as she had said, they’re friendship chocolates. Komura is a little disappointed but decides to look forward to next year’s chocolates.

A month later, on White Day, Komura struggles with the idea of giving Mie-san a return gift. He eventually decides to give her chocolates, but Mie-san, who has decided to cut back on sweets, initially refuses. After some persuasion, she accepts Komura’s chocolates, leaving him with mixed feelings.

The episode ends with Komura hoping that in the new school year, he’ll be seated next to—or at least near—Mie-san.
