I'm an Asian and around me I have not seen parents forcing their children or children agreeing to parents in fear. Time has changed. I think parents are ok with what their children want unless the parents have something better or dangerous plan in mind. I believe if this happened in common people's life (even common people dont listen to their parents now lol) but Sean, Esther, Mark, Mint are celebrities. They have freedom to go against their parents. If these celebrity children agree with their moms, I think even they want what their moms want in their mind.
In Mteam, if May (Mint's mom) was not involved or if Mint did not listen to her mom, I think may be Mark and Mint was talking to each other like friends even if they are not koo jins anymore.
SeanEst are my 2nd favorite koojin. I loved them for their off screen chemistry. I like Sean more than Esther though. He is a gentleman. Its easy for him to cry in emotional scene cos he is very sensitive guy. I hope he is strong in this situation. I dont want them to be like Mteam without seeing each other anymore. If Esther listens to her mom cos she also wants to be koo jin with Push, its wrong decision. Sean will not lose anything if she separates. Mom and daughter's dream also will not come true. Stay strong Sean.
