I did not once get frustrated by a constant barrage of contrived obstacles 'preventing' the main romance from progressing.
TBH, I'm not here for the angst. When a story takes place within a situation that's genuinely difficult to resolve, that's one thing, but I'm getting sick of romances than finally begin in the final episodes of the show, that drag on, and on, with rushed finish. This is not like that.

I was impressed that the early story was mysterious for a while, but resolved itself quite early in the drama, so we could get to see the couple spend some time AS a couple. It was very realistic that they gradually got better and better at resolving their misunderstandings, faster and with less fuss each time. I thought the pace was perfect.

I smiled so much, throughout this show, that I thought my face might stay that way. It was fun, heartwarming, interesting, and had several noble characters who got a chance to show their best aspects to come out in a better place than where they started.

I gave it 9.5 oput of 10 because I couldn't find anything to criticize about it. It was wonderful. It did everything I needed it to do.
The soundtrack didn't make me stop watching to go get the songs, but some were quite nice, and all fitted the story. At no point was the soundtrack annoying, or out of step with the feel of the show.

I will definitely watch it again, just because it made me happy to watch it.
Especially loved the boy who played main chaebol as a kid. ❤️
