Felix :)

You live in the House of Thirteen Cards because you're related to Fyodor and have a common business with him. Most of the clones liked your visit, but Felix always had a soft spot for you... He often watched you through the crack in your bedroom door, constantly protected you if Varu offended you or Romeo bothered you, and never offended you himself. He simply loves you to death. Even some of the clones noticed his behavior, but Felix didn't care.

Basically, you were talking to someone on the phone. At that moment, Felix came in, but when he saw you were talking to a man, he got nervous.
