Quan Si and Long Su both died. Unexpectedly, Quan Si woke up in someone else's body. It was discovered that he looked exactly like himself before his death, including his name.
"I used your body. I'm sorry."
Many years later, I returned to my former city and looked for him. Now Quan has the ability and courage to see him again.
Longsu, I'm here to see you.
Intention: Looking for Longsu
