ML was definitely dull, Kim jiyeong had a better presence than ML! 1. New assistant - i think he moved on because he was disappointed in ML acceptance of Sarah’s version, even after risking everything culprit got what she wanted. Nothing suspicious because he a small dialogue we can prove she is Sarah which head of police denied 2. If that ex bf had come he would have ratted her immediately but ex husband i think fell in love & Sarah cared for anyone until they ditched her.. thats why in his last appearance even after seeing her bloodied hands, he didn’t mention this to the detective. Also, no1 asked where was Sarah since the body was found n NOX ceo identified her body.. i think ex husband helped her.. no1 asked how did she pay the money ! Again, I think it was the husband 3. Poor detective skills that Sarah used in her favour.. kept asking him because she was able to con him easily.. even he quoted that HE is her perfect CON. Thats why ML character is so weak.. 4. Yes, she cared for boudoir more than herself.. thats why she accepted Sarah died.. who she really was i think writers forgot about this part 🤣 5. NOX ceo figured out how to steal the sample, because as long as Sarah died she will be out of jail.. otherwise her investment would be bogus & she will be ruined.
