Both dramas are historical/mystery genres in which the couple works together to solve crimes. The MLs are cold and initially uninterested in the more flirtatious FLs.

This one also has a revenge theme. It involves the parents including their kids and then there's the hidden identities and babies being swapped and just much more. I think you'll really love it you should check this out too.

It has the whole revenge theme here. I think it also started off with like parents and the kids I think you'll really love it check it out.

They're very similar with the whole revenge theme if you like that I think this would also be great for you.

It reminds me of history 3: MODC with how one of them was smart and quiet but the other one was more social. Even though in history our social boy was bullying our quite boy before he fell in love with him but I think the way one of the main characters had an accident from both dramas are similar so you will love it.
