Wei helps in class and is his girlfriend. But I called to break up, and I haven't heard from you since. This is the beginning of the whole story (here refers to the reason why I set out to find Wei and what happened). Wei was infected with the virus and broke up with him, leaving a letter to him, which was very sad. In episode 120, his friend left him a message "I seem to have seen Wei" on the ground. The first episode 123 was transformed by the black fire line, and it may have changed back from the corpse brother. Now I have boarded the plane and left H city safely, and I am receiving treatment.
