It's summertime and Sunoo was feeling lost. Lost as a person and lost in his feelings. He thought he can continue living life just like the good old days, but no. There was always something he couldn't make out hanging over him. So, he went to a psychiatrist, searching for the answer to his ongoing worries. Little did he knew, his life would be a mess starting from the day he lied to Sunghoon. Sunghoon on the other hand was restless. The thought of his special person leaving him behind made him scared. It pushed him into doing some unbelievable things. He doesn't care if others scorn him for that, as long as he can keep Sunoo beside him. [Sequel to Obsession] Start: 1 September 2021 End: ???
