He sexually harassed two people, Poppy and Pastel, although his actions towards Poppy seem to be much worse as he would randomly mention his cock a lot and you see immediately how uncomfortable that made her. He did some long public apology (which seems unnecessary in some ways, and also was damning in others, in which he literally considered trying to scare Poppy into shutting up) but he's never actually apologized to either of them. It's not like a one off joke or whatever, it was sustained harassment that was clearly unwelcome.
