This show has really good ML and FL chemistry, acting, and dialogue between them. Everything else is ok to actively detrimental to the show: the nonsensical business plots with analysts acting as hardened police detectives, the ridiculous tear allergy that doesn't really even matter that much because she just goes to the hospital and everything is fine, the absolutely snooze fest second couple which the show spends way too long on and doesn't matter to the main plot at all, the number of K-drama-esque cliches like people slow motion falling into each other and their lips land on each other...

The biggest sin of this story is how the FL loses all her agency. At the start she's competent and shows the ML that she's grown up from her past and isn't just someone who needs help all the time. The rest of the show is her needing help all the time. Her entire character arc builds to the point when she finds out about her dad's demise, but then the story doesn't let her do anything to giver her character resolution. Her very personal story about how her dad died due to corporate greed is written in a way where she contributes nothing to the outcome of her own character arc. She regresses and turns back into a damsel in distress.

Everything about the romance between the leads is really good. Their banter and how they interact is the reason to watch this show along with the cutest corgi who gets a lot of screen time. The only thing is you have to fast forward through so much drivel to get to the good parts. The show is at its best when the CP are bantering and the show revolves around them as a couple.

Pros:
Good acting
Great CP chemistry
Really witty, funny, cute dialogue
Most side characters get a good ending that feels true to their motivations
Lots of corgi scenes, dramas wish they had a mascot as good as Wealth
Most hilarious mother/son-in-law scene in any drama
Good last episode

Cons:
Bad character writing for FL
Horrendous secondary couple in terms of acting, writing, chemistry
More bad than good scenes with company politics
Lots of cliches/cringe moments like every race car scene, every fight scene, K-drama slow mo
Tear allergy that ultimately doesn't pay out in any creative way, they just forget about it after the introduction.
Really bad first episode

Overall:
Skip boring scenes with the second couple and boring company politics, watch for the ML and FL hilarious and cute banter
