Why? You may have watched farther ahead of me (I'm following the YouTube/Viki schedule) and maybe you've seen something I don't yet know about, but right now, her only "crime" is to crush on LX. But that's all it is - an infatuation - and while I would rather her get over it sooner rather than later, I don't hate her for it. Besides, from her perspective, it's not as if she thinks she's poaching on her friend's territory when JJ has only ever told her that she thinks of the boys as her brothers.
I actually feel bad for MingYue what with the way she's had to live under her mother's domineering thumb. No wonder she's confused about how she really feels and is easily swayed.
I reserve my hate in this show for people like... the three generation of women in LX's maternal family, as JJ once put it. LX's maternal uncle (who I seriously wanted to reach through the screen to punch when he accused LX of being responsible for his sister's death and being a cold, unfeeling son). And ZQ's sperm donor (as I refuse to call him a father, even a biological one). 😝
