Nanxing is sick, mentally ill, and has type Ⅱ bipolar disorder.
He couldn't help but take an overdose of meth during his depression period, and attended his own funeral the next day as he wished, until his body and soul disappeared after the first seven days.
At the funeral, he saw the young Bai Yueguang, whom he had a crush on, and looked at Chen Yiming wantonly, taking advantage of others not being able to see him.
Then he saw his own Bai Yueguang slowly squatting down in front of the portrait and cried.
"Damn it, I told you to change the photo to look better and put it here, it's so ugly!" Nan Xing regretted it very much.
Concept: The earth is round, so people who have missed each other can find each other again.
