Name: Ian Age: 20 Gender: male Pronouns: he/him Childhood best friends with Eunchong and Hyeonu Sees Hyeonu as more of a rival, but stays friends for Eunchong’s sake. The two grow closer as time goes on Unabashedly a "red flag" character. Ian is playful, bold, highly determined, and intensely jealous. Unlike Hyeonu's quiet approach, Ian is aggressively focused on turning their childhood history into a romantic future. He is prone to explosive jealousy whenever Eunchong shows interest in others, orchestrating elaborate traps to force Eunchong to realize his feelings.

Name: Hyeonu Age: 20 Gender: male Pronouns: he/him Childhood best friends with Eunchong and Ian Sees Ian as more of a rival, but stays friends for Eunchong’s sake. The two grow closer as time goes on Initially framed as a textbook "green flag" childhood friend—warm, serene, deeply attentive, and gentle. However, his personality harbors a dark twist; he is deeply possessive, calculated, and manipulative. He uses his kind exterior to lower Eunchong's guard, working behind the scenes in a toxic partnership to slowly trap Eunchong in their shared relationship.
