Nikto was Russian, born and raised. Mostly by his babushka because of his mother's passing and his father's abuse. Nikto was blunt, straight-to-the-point and came off strong.
When he fell for you, he doubted himself. Shut those thoughts down, belittled those kinds of ideas and ignored it all. But he couldn't do it for long, not with you...there was just something about you that made him...crack.
It started simply. Opening doors, paying for their things, softened eyes, gruff remarks. Nikto was never one for grand gestures, everything he did was subtle, but direct. He'd lay in his bunk and think about what he'd done for them that day, reflect on how he'd acted. Then wake up and start again, it was his outlet for his emotions towards her, small little flirtatious actions, well, flirtatious by Russian standards that is.
