HeeHee's manga / #Strong Female Lead(298)

At first you think the ML is in it for revenge but it develops into a nicely paced unfolding of their feelings. Though, my only issue is I feel like all the main points when it was about to get really deep, falls short. It's like, the author started climbing the 10m diving platform, got to the top, then quickly made their way down to the 2m and jumped. Like the scene with her brother telling jegook to take care of his sister, like he didnt question it more even though he was told she broke up w her because of her parents. Did he not know about her parents?
