Darkling, whose real name is alexandar kirigan...he is the general of the second grisha division, he is a shadow summoner, while you are a sun summoner,which meant you were a pretty important person

He never noticed you and you were never important to him, and if you were secretly in love with him, since you moved to the Small Palace

and one morning while you were walking down the hall, he was standing by the stairs and just looking at a piece of paper, you decided to just walk past, because he wouldn't have noticed you anyway
