How is she shallow and not 'worth it' for losing interest? What she's doing is perfectly right. Atleast she isn't leading anyone on when she's not serious.
Hahaha! What a joke. You're clearly in the minority in your way of thinking. She was all gung ho about getting to know Geonwoo romantically and, as if a switch was flipped, she suddenly lost all interest in him when she saw that drawing. That's pretty damn shallow. Who wants to be interested in someone who will instantly dump you when something "better" comes along?
they weren't even dating tho and all she had was a crush on geonwoo. all that happened was her no longer crushing on geonwoo. she isnt shallow for losing feelings it just means she wasn't really serious abt dating geonwoo.
Crushing on one person and instantly crushing on someone else certainly seems to indicate an extreme shallowness to me. Let's be realistic here. I'm sure that, before she suddenly flipped her switch to the gloomy 3rd wheel, you would have agreed that she was seriously interested in dating Geonwoo, though you would now strenuously deny it.
just give up on her. She definitely isn't worth your time. She was all googly-eyed about you, but she's such a shallow person that all it took for her to completely lose interest in you was a drawing of her by her "friend" for her to become all googly-eyed about him instead. You're wasting your time pining over someone who changes their love interest at the drop of a hat.
