Before Sang-woo can answer, Jae-young kisses him. It is not a gentle, romantic kiss—it is a bold, questioning kiss. Jae-young pulls back and watches Sang-woo’s face for a reaction.

Later, they step outside to “discuss” the project. In reality, Jae-young confronts Sang-woo’s emotional block. Sang-woo admits he doesn’t like Jae-young’s “careless” way of treating everyone the same. Jae-young, grinning, asks: “So you want me to treat you specially?”

When Jae-young later finds Sang-woo alone, he corners him with a direct question: “Are you jealous?” Sang-woo denies it with his usual cold logic, but his voice falters—a major tell for viewers. Jae-young, ever the tease, pushes further, leaning into Sang-woo’s personal space. For the first time, Sang-woo doesn’t push him away immediately.

However, some fan translations note that the Korean word for “error” (에러) is used in the webtoon as a coding term, but in Episode 5, Sang-woo’s internal monologue (not spoken aloud) uses “오류” – a more human, less technical word for mistake.
