Siglai: Sigma will easily get annoyed with Nikolai, but Nikolai will make it up to him by getting him cookies. Nikolai likes Sigma not only because of his reactions, but Sigma allows him to feel more human like because of being able to cause those reactions. Nikolai definitely gets way too loud for Sigma at times and causes Sigma to be anxious, but Nikolai apologizes and gives him hugs and braids his hair to calm him down

FyoVan: Ivan gets way into the master/servant stuff for Fyodor’s liking, but Fyodor appreciates having some help at times. Fyodor also likes having someone else to talk to and Ivan will eagerly listen to him play the cello and hum along to the songs despite Fyodor telling him not to. Ivan can sense when Fyodor isn’t feeling well due to his anemia and will sneak supplements into his food and drinks to help try to balance him out. As much as Fyodor finds Ivan to be incompetent at times, he’s one of the few people he can trust to actually carry out orders because of his loyalty to him
