MC was an orphan who got adopted since she was a child. First, she got adpoted into ML's family then after ML's parent got divorced, MC got re-adopted by 2nd ML's family. So, it wasn't at all like what the decription stated.

ML was Kiwook, MC's idol as well as her first adopted brother. Kiwook loved MC since she was still his sister while MC loved him as her idol (because she already forgot about ML in the past as the time went by).

2nd ML was Hyojun, MC's current adopted brother. I like him more than ML because he was more dependable and stronger than ML. ML tended to run away and hide when he faced with big problems but 2nd ML was brave enough to face anything that happened. ML always supported MC unconditionally but 2nd ML was able to offer more constructive suggestions for MC rather than blindly supported her. And 2nd ML was always there for MC, whether as a brother or as a man. I know in the end it would be hard for 2nd ML and MC to end up together because they're still adopted siblings but I still couldn't help but to root for 2nd ML more than ML.
