Byun Baekhyun has been in coma for 17 years, since he was involved in a hit and run accident when he was five years old. But the reason he's still in a coma is not because he couldn't wake up, it was actually because he doesn't want to. Baekhyun has a gift that allows him to lucid dream so when he starts dreaming up his dream world while in his coma, he doesn't want to leave. Who would? Especially when you're in a place that is your ideal perfect.

In the middle of his dream, he meets the the boy that looks like his childhood best friend who calls himself Chanyeol.

Everything was perfect. Was. Until Baekhyun got sick of all of it and told himself that he can't keep on lying to himself and avoiding the truth so he tries to wake up. But he can't. One thing he didn't notice, he was too captivated by Chanyeol and he wasn't paying attention to the fact Chanyeol was pulling him deeper and deeper into his dream. It was as if Chanyeol had taken over Baekhyun's dream and isn't alllowing him to leave.
