Warnings:
1. If you don't like snakes, please leave right away.
2. This is a modern urban story with some added elements, such as demonization and beast transformation, but few people can use their abilities.
3. The seme and uke are excluded. The seme's name can't be changed, so here's the correction: Lu Tinglan.
