TRIGGER WARNINGS of this series: Infertility issues, illness, death.
Comedy is on the thinner side and there is also melodrama.

Looking at the ratings of this drama I feel like I watched a different one than everyone else.
I really wanted to like this series because the premise and the start had potential and there are things I liked in the portrayal of flawed characters that don't do the best of things, but sadly this just progressively lost me as episodes went on and things started to annoy me.

Overall my main two issues here are:
The execution of the plot is a mess at times, it wants to do too many things at the same time but none are necessarily solved or are just there for the pure chaos of it, it got kind of boring. I certainly didn't expect to find this show boring considering its length and how much I wanted to like it because the characters are not presented as perfect like in many other dramas. At points I felt kind of disappointed in myself for not finding it engaging enough but I literally fell asleep a few times, and I never fall asleep with series or movies. Funny enough is how I didn't even bother in going back and I don't feel I missed anything even though I missed in total probably about an hour and a half or a bit more of the total series.
Until the later episodes most of it it's just going and coming from places without enough of a substance to me, felt like a lot of padding. They're just looking for the potential father while he's dragging the girl around and the other two are following them, and the scenes with SML's mother and all that I still don't know what they added to the plot.

The second worst thing in this drama is once again the obsession with the bloodline. At points I thought it was presenting different ideas here because of the main characters and the plot in general, only to fall into the same silly ideas with the blood and how once you see your parents "you know" just because and unconditional love and blah blah blah. Equally silly was the expectation that some dude that might be his potential father would care about him just because he gave the sperm once, this is when they were theorising what that potential father might do or not for him as well as potential inheritance. And then only in the end to go back to a father that was a piece of s*** and abandoned him back in the time. "Oh, but he did go to the school though!!" someone might say, yeah, and after he was missing he didn't move a finger to find him, and apparently didn't care about her blood daughter either. I get ML needed the closure so to speak, but he said it more in the line of getting back some kind of relationship with him again, what falls again into this korean idea that parents don't do wrong and that at the end of the day everything needs to be forgiven because they're your parents, blood and "unconditional love" again.
The whole series revolves too much around "daddy issues" and I'm not a fan of this plot device.

I get it wanted to be comedy at some points but at times it was simply bad taste to me, like how FL wanted to take that baby in the beginning or when she takes ML from the hospital towards the end.
I also didn't appreciate much the duality of going from comedy to melodrama from one scene to another. I don't like melodrama in general either but I think that the comedy bits fell even more flat at times when straight before or after everyone was having a melodramatic moment. One second they're crying about something and the next it's like it never happened and everyone is happy to then remember and cry again.

There are quite a few side characters for such a short drama and I don't feel any of them was explored in depth what it would be fine if it wasn't because it feels they wanted me to care more about them than I did. SML is explored more but it could have been better in my opinion, his whole personality is more or less following the girl all around for most of the drama and it's progressed quickly to have his ending as it is.

I liked the ML for the mess he is, but I would have liked a tiny bit of growth, why is everyone still following him around when he's trying so hard to push everyone away? just leave him get lost then. It's funny that of all the things he did that was the worst for me, because as a viewer this dynamic got repetitive. He's a bad person but a good character, but I wish there had been some progression and that we didn't get the same dynamics of him rejecting people to then leave to then the others try and follow him, it got old quickly.
FL was ok for the most part until she started annoying me with her extremely childish tantrums, she spends half the show screaming. So she might be a good character again but in her case I didn't enjoy watching her.
Her side of the story is never explored enough anyway, we're given some pieces but there is never more exploration about it. She didn't even ask the bio mother anything either, she just spent the time screaming once again. We're also not given any other answer or even conclusion to her menopause thing, because it's not a black or white topic that it's how they presented it here, she's told, that's the end apparently. Her character in general revolves too much around ML and she's just a girl with two personality traits.

The ending was expected considering how the show starts and still was a bit anti-climactic in my opinion, even more that credits scene with the car driving, it's that FL with ML's body inside or what? It also felt a bit rushed since we got so many bits of their trip in a few scenes, I really wished this had been a good chunk of the drama instead of the thugs pursuing them in the first half for example.

Overall it's not an awful drama and it can be watched. I wouldn't rewatch it personally and I wouldn't recommend to people that wants happy endings, perfect characters nor to those that might be triggered by some of the topics.
