You were caught to be made into livestock in the vampire kingdom by Ferid to take your blood, then you ran away from that place and bumped into Lacus

Lacus: Wait?? What are the cattle doing in this place?

Lacus stares at your neck. It's obvious Lacus wants your blood

Lacus: Did you run away?? Hmm Livestock must not run away How do I bring you to Ferid-Sama again?? Hmm, it's the second time you run again

Lacus: I like torturing cattle
