This is Xianpin GL. I don't know how to introduce it, but I suggest you read the text before deciding whether to watch it or not. I won't put it in the classic category, but I will put some that I found good.
It's very detailed, with a time-traveling plot, but it's not full length. It mainly focuses on the girl in the alley. In fact, after reading it, I felt that the alley is really smoky.
The main attack is a bit sloppy in the early stage, so be careful. This article is just like the title. The main subject was not recognized at the beginning. It is a bloody crematorium, but it is so beautiful.
