After reading the first chp of season two in KR I think there was a mistranslation in the official EN where Hwibum is talking to his friend about Yeonwoo.
Because the EN makes it seem like Hwibum told his friend he was seeing a guy, but based on the 2nd season he either said it was a girl or his friend assumed it was. Because the friend definitely has no clue coming in that they are dating or that Hwibum is at all into guys.
Maybe spoiler, so beware...
