Sunoo isn't popular but he isn't an outcast. He liked not being the center of attention but not hated. No one has a reason to hate him until his one secret gets loose.

sunoo wears only black shirts with different prints on and riki decided to annoy him through buying the same shirt and wearing it to match with him on a daily basis everything seems fun to riki until he learned about sunoo's past experiences

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: ???
