All over the place

So I just binge read and apparently everyone got there own issues...

Let's start w the dead dad. They seemed lovely dovey so why the sudden step son? Paternity test seemed like a concept. Also why can't mom see her own child? She doesnt seem like an addict?? I wont be surprise if the throw rivaling inheritance issue later.

Who let that witch in the house? A complete outsider was able to drive the legal wife away?? I was thinking the grandpa made it so, but he also doesnt like her? What.

Let's move on to secretary Yoon....she was clearly always with dead mom so how did she "infiltrate" the company? She a ghost or sumthin? Nobody notice her connections?

Let's not forget the biggest plothole the missing dad. Why is he so gullible he decided to kidnap and kill a random child just cause someone ask him and even out on the streets lolololol.

Why do I feel like author just adds the plot along the way. This is the typa teledrama I watch in tv LMAO. I'll stay just to see how more ridiculous this whole mess could get
