I can totally see, how she is really unlikable, but I think trying to hate on her won't make the character easier to read.
I'll just try to read her panels with a positive thinking BECAUSE in the end, her character in total doesn't do anything for the plot (for now), as example; You could have skipped the first few pages and it wouldn't have changed the story in any way. She is just there, not adding much.
And tbh, Lihuan would have done something like giving flowers anyway, his character wouldn't have come up with it on its own, so Djun needed someome to push it forward.
ITS HARD TO EXPRESS MYSELF IN ENGLISH IM SO SORRY....
The girl took even a bigger turn to the worst. I can't understand why people are defending her behaviour?? She's creepy as fuuuuck. Someone like her would be utterly terrible to be around IRL. Sure you can say that B-BUT THIS IS FICTION!! Yeah ok but this is also reality TO THEM. It would be more understandable if she was a stupid kid around the age of 13-14 but since this takes place in a university in China she has to be at least 18. Yikes.
