**Major spoilers: Unless you're updated to ep 21 and have seen the previews of ep 22&23 I would advise you…
I genuinely believe that the 5th sister is involved with Mrs. Liang's death/murder. It's the perfect play to get RSB mad and move against her grandma's wishes and thereby replacing her.
I made a serious mistake watching this series! It is so good that i wish i waited for it to finish and then binge watch. Waiting for new episodes hurts 😓
Idk if you're still interested after two years lol
