Yeah, that's why i left this comment, because it seemed to me like quite a few people were misinterpreting it as cruel or rude when if you actually look at what he said it isn't that bad. The text is: Bum: "you should stop." Jumi: "what?" Bum: "Standing between me and Yoo Won hyung... you should stop. Theres no need to do that anymore. You standing there is really uncomfortable." Jumi: "what are you saying? OHHH!!! Hey, LOLOL. You're upset that Yoo Won oppa was only talking to me just now, right? Is that it? As expected Kang Hee Bum's the king of obsession. You have nothing to be jealous of, so you get jealous of the relationship between Yoo Won oppa and i. Don't worry, when its time to step away i'll do that.19 yr old Kim Jumi is not that oblivious." Bum: "yeah. This is only hard for you. I'm saying its pitiful for you." Jumi: "what? i think you're misunderstanding something. I... It's not that i... like Yoo Won oppa." Bum: "i know."----See it yet? He knows how she feels about him and is just telling her not to put herself in a position where she'll have to watch the guy she likes be with someone else. He doesn't have issues with being her friend, he literally says "i'll always be there for you" when she asks if he's "done with her now that he's with Yoo Won". He is literally saying that they're still friends and, not to be rude, but what he says is more important than what you think is happening. I'd suggest reading through it again.
If someone calls you over the normal thing to do is to go over to them...
Yes, the words he says after show that he didn't intend to be cruel. But the first sentences--the first ones--sound very hurtful. And saying she'd be pitiful is hardly comforting, either.
AGain, it's the phrasing. The first sentences are all sounding very accusatory and mean. That he explains it later in, again, not the kindest way, just adds to her humiliation (hence her lashing out).
How one says a thing matters.
What? you can't just look at the first part of what someone said and base whether or not they're being an asshole on that... You have to take EVERYTHING he said into account... He isn't CALLING her pitiful, he is saying that the fact that she has to have her feelings hurt by watching him with Yoo Won is pitiful. There isn't even any accusation, you're literally just making it up in your head.
I realize that the way Hee Bum said it was really harsh, but i don't think he said what he did with the intention of hurting her. It seemed obvious to me that he noticed her feelings, probably both him AND Yoo Won noticed actually, and he didn't want to see her suffer anymore so he told her to stop tagging along when he and Yoo Won go out because it is inevitable that they're going to act lovey dovey at some point in front of her. If you noticed, neither of them has even TOUCHED each other while she is present until this chapter and even here they hid the touch. I think that Hee Bum is actually trying to be considerate, if he'd continued to treat her the same way, what with all the late night meetings and alone time together, she might NEVER get over him and might just continue to fall for him, like she did up to now because of their interactions. I don't think he is telling her that they can't hang out anymore, just that there needs to be some distance between him and her to let her get over him, i also think that he is telling her that if he and Yoo Won are going to something like a fireworks show that she shouldn't play the third wheel because it makes things awkward for him and Yoo Won considering that they know how she feels and it is just going to hurt her once they decide that they aren't willing to give up skinship for her anymore.
