About

Guest and Lee Jinhyuk start arguing over a very minor issue. At first, it seemed like something they could easily brush off, but as emotions intensify, the pent-up resentments they've both been holding back begin to explode one by one. Misunderstandings and disappointments that went unsaid for a long time surface, causing the fight to escalate. Currently, the two attend different schools—an all-boys high school and an all-girls high school—so they cannot meet often and rely heavily on messaging. Because of this situation, even small problems aren't easily resolved, and ultimately, their hearts only drift further apart.
