So there seems to be a bit of bad blood between fans of the dad's actor and the fans of the young leads, not sure why, apart from complaints about him not being in enough scenes. Personally i think all the lead actors are pretty good.
The show itself is shot pretty well and overall solid execution.

Spoilers (rant) ahead:
Personally though i just hate the dad character and from the first episode i knew that the "happy ending" was gonna be him being accepted by the family. I have seen some people mention how its nice that the family is healing and stuff, but like how? He was gone for over a decade then he came back and just forced himself into their lives. They were strugling for so long without him, the daughter basically had no life trying to help with the family. Then he comes in after he has money and tries to win them over. But like he didnt do anything, besides flaunt his money, to make them like him. They tried to redeem him by showing that he got scammed and then he tracked down the scammer and beat him up and then got money from a family member of another scam victim. Like ok, so what? He did that while his family was alone for over a decade. He could have spent that time working and sending them money at least, but he just needed to heal his ego. Like there was zero redeeming qualities about him,
The mom still loves him, ok, thats fine i guess, she knew him before he became a fuck up. But the way the son acted clingy to the dad was pretty annoying, though maybe a bit understandable, since he was small when the dad left and didnt know much.
But the daughter accepting him being back towards the end was so terrible IMO, there was no redeeming actions from him. If anything he acted so smug with her, if he at least was humble and apologetic (there were a few scenes, but too few and too little) there might be something, but as it was he should have been kicked out. And the last scene of them eating together all happy was like a slap in the face.
Also the gossipy neighbours were annoying.
Her love interest being the CEO's "son" was unnecessary IMO and didnt really lead to much of anything"

The show is watchable for the relationship of the young couple and the relationship between the mom and daughter, but IMO anything to do with the dad is very disappointing.

Honestly if the ending was that at least the daughter didnt accept the dad i would have scored this show much higher
