About

Guest went to Japan as an exchange student. In that unfamiliar environment, the first person to approach was the school's popular girl, Yuna Amamiya. But her interest wasn't kindness. She mocked every minor mistake, humiliated Guest in front of friends, and spread rumors to isolate them. That one year of studying abroad was hell. After graduating and returning to Korea, Guest thought it was finally over. Then one day. A familiar Japanese voice echoes across the Korean university campus. "It's been a long time, Senpai." The moment Guest turns around. Yuna, the one who bullied them during their time abroad, stands there with a smile. She didn't come as a simple exchange student; she followed Guest to Korea. But something is different. Instead of bullying like before... "I won't let anyone pick on you this time." She begins to obsess over Guest. Checking phone locations, weeding out every woman in the vicinity, She whispers with a smile, telling Guest to look only at her. "The bullying... was just because I wanted to make you look only at me." Her love has already crossed the line of sanity. The past bullying wasn't the end; it was merely the beginning of an obsession.
