Generally I've found that whenever a lakorn has a male lead who's super angry and spiteful at his father, the rest of the show turns out to be a hot mess. This is no exception. While I can't deny the addicting quality the show had on me, I can't say the story and its characters were all that great and at times had me shaking my head.

We have our hero (or should I say anti-hero) Pan, who's angry at his father for having a mistress when his mother was still alive. It doesn't help that after her death, he had his mistress and her son move in with him and work at his dad's company. There is reason for Pan's anger, which gets even more inflamed when the mistress' niece, Pai, comes in to move in with them. Pai herself has been forced to move in after her grandpa's dessert shop is seized due to failure to pay rent.

This is pretty much a family drama with some romance in it. It's centered mainly around Pan and how he deals with his unresolved issues with not only his dad but also his step-family. We do get to see some cute moments between Pan and Pai, as both are hot-headed and bicker with each other a lot. I like how Pai is able to stand up to Pan and see through his anger, and pretty much be the only person who can get through to him. Pan also cares for Pai, and it's sweet to see him grow to love her. Unfortunately the OTP scenes (and Pai's role) get reduced near the last third of the drama in favour of the Pan/Pan's dad issues and conflicts regarding the 2nd leads. It gets even worse in the final episode where they introduce a new conflict between the OTP and it's basically used as filler until the last five minutes where they finally get together. It was pretty dumb tbh.

There were a lot of wtf moments that really made me shake my head and ask why. For example when the villain (which is the 2nd FL's dad) steals Pan's dad's company right under his nose. I thought Pan's dad was stupid for not realizing that he obviously had bad intentions, and he even knew that the villain's company was bankrupt and was in need of money. I felt like that could've been completely avoided and I wonder how Pan's dad could be a competent businessman. Ek's infatuation with Pai was also just weird; they're cousins, so it made no sense that he would love her in that way. Another wtf thing was the 2nd FL; at first I found her to be super annoying bc she was constantly pining for Pan and committed some heinous crimes to make sure no one stood in her way. We later find out that her dad hypnotized her into thinking Pan loved her, and basically used her to save his business. In a way, I did feel bad for her for having such a scum dad but even after she found out she forgives her dad (wayyyyy too easily) and continued being an annoying b*tch. Her end was pretty satisfying, albeit also sad but it made up for the terrible things she did.

I will say that what I enjoyed most about this lakorn was the reconciliation between Pan and his dad. Although his dad may be dumb and hot-headed, he truly has a good heart and raised Pan as his own even though they weren't blood-related (he also treated Pan's mom really well even though he knew she was pregnant with someone else). It was sad to see Pan's mom be a victim until her end, as she was not only r*ped but also misunderstood by Pan's dad. Pan's actor did a really good job crying his heart out and begging for forgiveness when he realized this, and I too cried along with him. 
Overall I did enjoy the show for what it was and above all else it was entertaining. Music was also not bad. I'd recommend you watch if you don't mind the above shenanigans and have the time. Would not re-watch however.
