Girl knew that he was in love with her brother for the very start and still went on to marry him and have sex with him thinking she could change him
Exactly. As messed up as the ML was for doing what he did, it really did prove that Lejoon who always made his sister a priority and put her first, and yet the “mother like” sister who raised him didn’t give a flying F about her baby brother’s relationship and respect the fact that he was in love with ML and vice versa. She just fell at first sight which let’s be honest, she just liked his looks and wanted a man like that for herself and basically started looking at her brother as competition like a catty female. That’s disgusting and the fact that she turned it all around n made herself into the wronged victim in the situation as if she were tricked or lied to, but she was told straight up from the very beginning but chose to ignore it/not take it seriously and pursue him anyway cuz she’s a selfish b!tch. That doesn’t sound like a good older sis that raised him. He’s way better off without her.
This story is messy in all the ways All the characters are messed up yes but I hope that fuckass sister have a miserable life, MC’s fears was proven right because she’s a homophobic price of shit.
