I'm afraid Levi meant Hayans orphan kids as to lure her and Euntae or emotionally manipulate/demotivate them, killing or turning them into vampires.
Looking back at the prologue, you can see the two kids, the late father figure/priest and probably Euntae.
Ah damn, the author is definitely playing with our emotions (╯°Д °)╯╧╧
Seme going down on uke was fucking hot, it would've been better if he stopped the pounding however when the uke told him so#-.-)
