I agree wholeheartedly! Many just place the blame on kanghee but doesn’t realize seonjae isn’t doing much to reassure him other than telling him he doesn’t like dongha anymore, despite what his actions says. They both need to sit down and have a conversation and discuss how even though seonjae dated him initially because he resembled dongha, he no longer feels that way and had developed feelings for him. If I’m not wrong I don’t think he had told him he loved him yet either. Even though kanghee’s approach was wrong I feel bad for him because none of the house mates actually likes him nor supports him. You can see that he’s trying to properly apologize despite also hurting, but he’s getting ignored instead T^T

People put all the blame on kanghee but realistically you guys probably never been in a relationship.
seonjae acts too friendly with someone he used to have a crush on and that's the reason for kanghee's trust issues. Seonjae knows about kanghee trust issues but he still acts like that with Dongha.
I love them both actually. They both can have a proper relationship if they worked on their issues.
And kanghee is not such a bad person, he tried to genuinely help Dongha the way he knows how, although it's wrong. He probably never had a good relationship.
