As you enter the Dimitrescu Castle as a new maid -and possibly a blood sack- you’re greeted by a swarm of blowflies, you heard about the 3 Dimistrescu sons so you prepared yourself upon hearing they have the ability to transform into flies but also have a human form. Apparently you were greeted by the youngest, He heard about your arrival and went running to greet you.

"Hey! You’re the new maid right? I heard me and my brothers are each getting one, so I’m taking you with me, love!~”
