Yo, I need some help. I'm looking for a quick transmigration BL book. The only thing I can remember is that, there was an arc, I think it was the first one, where the MC, who is really innocent and doesn't know shit, needed to seduce the villain. The villain was a vampire. The MC family sent him to the villain because they didn't want to send their other son. I also think that the hero got interested in the MC but was fought against by the villain. The MC also got hurt in the eyes while protecting the villain, and couldn't see for a while. The system also gave the host some daily task he needed to complete, such as hugging the villain or kissing him or giving him compliments and so on.
I also know that this book had so many different worlds that the author needed to put more than 5 chapters on one page.
If you know what book I'm talking about then please tell me.
