I'm quite curious if Xing Wu and Qing Ye are cousins by blood bcz Xing Wu's mom said that Qing Ye's mom is her sister so i was wondering if they are cousins by blood bcs that wouldn't be appropriate right if they got together and they're cousins by blood. So i was thinking maybe his mom and her mom are like sworn sisters or what.

But, after watching just a few episodes i know that I'm gonna be obsessed in this dramaa. As far as i know, this and Speed and Love was written by the same author so I know that is gonna be a HIT one. Although, SAL and Dazzling are different tropes this gives me that same vibe like ML is poor and the FL were rich.
