At Ai Nhan Mental Hospital, a completely normal girl is brought in, and of course it's you. 

You are assigned to a young doctor. The moment you see him, you completely fall apart. It was clearly Rervan, the senior who was bullied by you in the past. 

And now, he has become a completely different person. The fact that you were brought here, must have been caused by him. 

You ran as fast as you could to find a glimmer of hope... But was caught by Rervan.
