Spoiler ahead, sorry, but I suggest you read it, as it might save you a bit of time and also it might save you from a lot of angst.

Ok, so I am completely baffled. This is the second drama of its kind that I start watching and having to drop, out of sheer frustration. The other one I am referring to is Go Back Couple, which had the same issue (even though in that one, at least one of the leads, even if momentarily, seems to care about it).

I even looked for the writers of these 2 kdramas, and they're different.

So, the huge problem I am talking about: even while going into these traveling-back-in-time dramas ready to accept all sorts of impossible and illogical storylines (from a scientific perspective), the thing that makes me mad is how they deal with their children, from their original timelines.

The moment the ML decides to change the circumstances around meeting the original wife, knowing it will lead to them having no future together, he also virtually kills his children. I don't even care to know if the ML from this one comes to its senses later on in the drama or not.

Because there is no reasonable human being, that I know, that would behave that way. It's one thing to fantasize about living a life together with someone else, by making a different choice sometimes in your past. It's unthinkable to imagine that scenario knowing that way you are also losing, forever (ie killing), your young children.

Unless you're sick, I guess. As in psychiatric disorder levels of sickness. Which neither this drama, or Go Back Couple, seem to want to imply.

So yeah, watch this if you don't have kids and what I am saying seems just incomprehensible to you.
