Chase You

During Do-Yun's childhood, Su-Hyeon, a university student, became his tutor for several years, and this marked the beginning of Do-Yun's first love. However, contact with Su-Hyeon abruptly ended without warning, and years later, they reunited at university as student and professor. But unlike Do-Yun, who is inexplicably overjoyed to see him, Su-Hyeon distances herself, and he senses the atmosphere has changed...

Simultaneously, he hears strange rumors about Su-Hyeon among his peers, and thus begins Do-Yun's desperate, reckless pursuit to get involved with him.
