Do Bawoo, quiet and well-mannered, once confessed his feelings to his popular and outgoing friend Ji Hoon. But his emotions weren’t fully understood, and Ji Hoon only remembers it as something between friends. Now in college, the two remain close, but Bawoo is gradually growing tired of their ambiguous relationship.

In a whirlwind of emotions, Bawoo proposes to Hoon, 'Let's date for just one week.' Hoon, seemingly in disbelief, replies, 'Okay.' However, Bawoo becomes even more confused by his reaction and gradually feels hurt by Hoon’s attitude, which doesn’t seem to take the proposal seriously.

Bawoo agrees to work on a webtoon project with Hamin, and the two begin working together. Meanwhile, Hun misunderstands their relationship as a "stalking situation" and starts to keep Hamin in check. Hun expresses excessive affection toward Bawoo, while Hamin sincerely approaches him. Caught between the two, Bawoo becomes emotionally confused and tries to sort out his feelings through writing, but the situation only grows more complicated.

As Bawoo is about to grow closer to Hoon at his house, Hoon suddenly wakes up and catches Bawoo off guard, prompting him to leave in a panic. Later, Hun misunderstands Bawoo’s confession as a fake one made just to push Hamin away, and brushes it off with a casual “Thanks.” Hurt by this, Bawoo becomes increasingly cold toward Hoon and eventually tries to end things, saying, “That talk about dating was nonsense.”

Hoon looks at a guitar pick Bawoo once gave him and recalls old memories. Bawoo is emotionally stirred by Hoon’s cryptic comment, “There are only three days left,” and grows closer to Hamin in the meantime. Then, Hoon lies about being sick to get Bawoo to meet him. He tries to lighten the mood with a playful attitude, but Bawoo asks, “Don’t you think something’s gone wrong between us?” as he tries to sort out his feelings.
