Yeon-woo's taking the lead again, huh?
Rosa really lashed out on him in the previous chapters because she really wants to posses him, and steal him away from her own mother... to the point that she wished it was her who found him first and saved him instead of her mother.
We get to see more his thoughts and perspective, and he's really freaky.
Accepting even hate from Rosa just as long as it meant she still has her eyes on him... he really enjoys it.
So I guess we got confirmation from both Rosa and YW and they don't want to end their little game... even after Suryeon and YW marries. They don't care even if they ruin the 'family' her mom is trying to build.
The family isn't normal in the first place if the new dad is your daughter's age (but I guess rich people typically care about morality).
Yeah... it's a f*cked up family... The mother (without warning) introduced a young guy as her soon-to-be-husband and father of her daughter who's his age is just...
