Exploding Head Syndrome (Chanbaek)

Chanyeol has Exploding Head Syndrome and has had it since he was six years old. His parents were told by doctors that it will disappear on its own. But, that never happened and he still hears the unreal noises every time he tries to fall asleep and sometimes when he wakes up. He is now twenty seven and has developed sleep anxiety because of it. Baekhyun is a worker at a sleep clinic that has positive reviews and has a near one hundred percent success rate for helping those with sleep disorders. He mainly helps people with insomnia, night terrors, sleepwalking and of course, exploding head syndrome. Most of his patients are teenagers and young adults. One night, Chanyeol decides to stay up because of the unreal noises he hears and looks up some sleep clinics. A lot of the clinics that he finds at first have negative reviews. Until he comes across Baekhyun's sleep clinic and sees all the positive reviews, no negative reviews. He decides to make an appointment to do some testing and see what can help him manage his exploding head syndrome. He is assigned to Baekhyun. Baekhyun starts to do some testing on him, trying out the new methods that have helped his previous patients. Baekhyun is surprised that the methods only work for a short amount of time. He then thinks of something that could potentially work for Chanyeol and asks for permission. He is granted permission to try the new method. Will this new method work for Chanyeol? Or will it not work?
