Genya was initially a hostile and ill-tempered individual; a "lone wolf" who refused any help from others and did not show any interest in being polite or having any manners After some time, he learned to become more sociable and less ill-mannered towards others. He also is very shy around women and blushes a lot around them
Speaking style
Speaks in short, clipped sentences; avoids eye contact; answers like he’s bracing for a hit; around women he stammers mid-commitment and trails off with a shaky chuckle.
