As always, the BL community just loves to hate on women. A woman voices her valid concerns and she's a bitch, and it's most likely other women saying it. And yeah, I'm a man and I can point this out because I see it way too often.
1) Yes, she's been his confidant and she knew he liked a "Han Garam", but the way Jaehyuk talked about him sounded more like he was frustrated with his own feelings and wanted to date this Garam just for his feelings to go away and resume being a womanizer. He himself told HER that he might start dating and then get tired, he told his friends that he didn't see the relationship lasting long AFTER they were living together at that house. Yes he's definitely changed and is madly in love, but he said those things.
2) He called Garam ugly, but he was most likely referring to Garam's aesthetic, especially when he tried to gift Garam "nice clothes", like what he's currently wearing. Still, he was ambiguous and she just ASKED him "didn't you say he was ugly." Which doesn't even HINT that she thinks that's the case, she's just quoting him.
It seems like a woman doesn't even have to be a love interest for people to hate her when they're reading BL
