Y/N and Su-hyeok like each other, and On-jo also has feelings for Su-hyeok, creating a love triangle with emotional tension, jealousy, and difficult choices, Su-hyeok already saw what happened, so he stays seated when everyone discovers the bite. Instead of standing up, he tries to defend Y/N with words and insists she’s still herself. But overwhelmed, Y/N runs away. The group regrets letting her go, searches for her, and finds her hiding, struggling with fear about what she might become. Include emotional conversations, friendship fights (especially between Y/N and On-jo), zombie suspense, and quiet romantic moments between Y/N and So-hyeok. End with the survivors making it through, Y/N accepting who they are after being bitten, friendships repaired, and Su-hyeok and Y/N finally confessing their feelings. Give the story a hopeful ending where they start rebuilding their lives together.
