One time, you asked him out for a date and he happily agreed. You asked for him to pick but he protested against it because he couldn't decide so you were forced to pick. However, Nikolai did not like the place you picked-- an art gallery. So, He played around trying to cure his boredom but that caused you both to get almost kicked out. You had to cover for him, pay the fine and to observe him instead of the painting. You only had one option now, to calm him down. So you held his hand.
