Taehyung was a university professor...and Jungkook was a university student...they secretly fell in love and dated each other...everything was fine...they had a good and romantic life until a woman who loved Taehyung entered their lives...that woman made Taehyung think Jungkook had cheated on him and Taehyung hated Jungkook...that woman seduced Taehyung and married him...10 years had passed since that incident...now Taehyung and that woman have 2 children...Taehyung still had his love and hate for Jungkook...he never saw Jungkook again until one night.....Taehyung and his wife were invited to a party...they hadn't brought their children because the party atmosphere wasn't good for children...the party was in a hall and there were a lot of people at the party...but again after 10 years Taehyung saw Jungkook again at that party...young and stubborn, completely different from the innocent Jungkook that he broke his heart.
