My Final Happiness - Episode 5

Introduction: The day my girlfriend got back together with her first love, I boarded a plane bound for Brindlewood. She told her first love, "Craig was just a fling. I won't have anything to do with him anymore. From now on, I'll only be by your side." Her friends all worried I might cause a scene. But they didn't know—this time, I wasn't going to make a fuss. Before leaving for Brindlewood, I had promised my mentor I'd join his medical research program. In just two weeks, I'd lose all contact with the outside world and dive into a secret project for the next ten years. From that moment on, there would be no ties between me and her anymore.
