TL;DR - Standard rom-com with a yandere twist that I didn't appreciate. 2ndary storyline and supporting cast make it worth watching. If you have time and like rom-coms, go for it.

If I could give this a 7.25, I would. I went through all kinds of emotions that I didn't expect to from this lakorn; I was confused, enamored, disappointed, bored and ultimately satisfied in the end. The beginning was confusing for me because the family relations were not explained properly, and it took about a quarter of the way in to figure out all the relationships. I would like to explain them briefly below in case you're interested (if not then just skip the next paragraph for my review).

The FL (Fah) has a bio sister named Dao and an adopted brother named Tawan/Nuk. Fah's parents took Nuk in when his parents passed away, although her parents also passed away at some point. Nuk's mom was estranged from her dad (Nuk's gpa) bc she married someone he didn't approve of. Nuk's gpa is a boss of a big jewelry conglomerate. Eventually when Nuk got older, he went to live with his gpa to learn the business. Nuk's gpa has 3 kids; one is Nuk's mom who died, his adopted gambler son (he has his wife and 2 kids who are the main antagonists) and his daughter born from when a housemaid drugged him (she has her own son). Nuk is forced to marry Pink, who is the daughter of the guy who gpa tried to set Nuk's mom with and niece to our ML (Neung). The drama starts with Nuk's wedding and Fah trying to stop it, only to somehow end up marrying Pink's uncle, Neung.

I found the beginning to be pretty cute and although this wasn't an addictive watch for me, and there were illogical holes here and there, I enjoyed what I was seeing up to ep 22; this was where the problems started for me. To start off, I have to talk about Neung. I liked Neung a lot, not only because he was handsome, but also he was a gentleman and treated Fah very well. I was pretty enamored of him until he got all yandere with Fah after he found out she was talking to Nuk behind his back (he thought Nuk was Fah's lover at this point). He took her phone away (I think he broke it), tied her up in the bathtub, gagged her and screamed at her while (I think) spraying water at her (I'm not too clear on the details bc I hated this scene and don't want to revisit it). Like I agree that what Fah did was wrong, and sure he did it to protect her, but this still felt incredibly extreme and I felt like he could've handled it differently. I was even more disappointed with what happened after, when Neung tried to make up with Fah. His apology was more or less like "I'm sorry for what I did...but if the person doing this to me was someone I loved, then they probably had a reason for doing this and I'd understand." Like wtf, how would she know that - you two are still keeping secrets from eo and that's not an apology. An apology is owning up what you did and that's that. I felt like the Neung I'd been watching all along would be better than this. This event ruined my view of Neung and I just couldn't love him as must as I used to.

When I stopped loving Neung, I subsequently stopped being invested in the romance, and the illogical things that I'd been ignoring or suspending my beliefs for came up to bother me. Some of these were: 
-Neung insta-loving on Fah
-Gpa's actions making no sense. He hates his daughter for being lowborn even though she's the one who loves him the most, but gives chances to his adopted son who's clearly a waste of space and supports his family who are clearly incompetent 
-The villains were a joke and made very dumb decisions-The storyline with Fah and Nuk's parents was messy
-Why did Pin (villain's daughter) still try to go after Neung even though he was clearly married?? They never interacted b4 that and her mom was encouraging it, even though she'd look like a homewrecker. 
-Why couldn't Neung tell Fah that him liking Pin was a ruse??

These were some of the things that made me feel annoyed and I eventually FF-ed due to how predictable things got. I will say, this part of the lakorn was not a lost cause; the storyline between the 2nd leads was unique and carried the lakorn for me to the end. It's funny bc at first I didn't care for Pink or Nuk, but they came out as my fave characters out of the entire show. Pink's circumstances with her pregnancy were unfortunate, but she stayed strong and classy throughout the ordeal, and you could understand where she was coming from. Her relationship with Wut was loving, mature and full of understanding. I couldn't tell if Pink would stay with Nuk or be with Wut, and would've been fine with either. Nuk was amazing as a great older brother, competent worker and a good person overall. When he learned about Pink's circumstances, he helped her and Wut out. He was there for Fah and Dao and took care of them. He was someone who you'd want to have in your corner, and became my MVP for this lakorn.

The supporting cast was also great, especially the dynamic duo of Dao's manager and Chang. Grandma was also awesome. The storyline of this lakorn got better near the end when everything was revealed, and I got back to watching in normal speed. Everyone got what they deserved. Due to the goodwill I built with most of the characters (even Neung), I was pretty satisfied with the story and character progression, and was overall happy with the ending.

All in all, I'd say this is a typical Thai rom-com (except the yandere part) and everything from the story to the music was pretty standard. The 2nd and their story was the only thing worth watching. This is an easy watch, and if you wanna pass time, I'd give this a go. I do wanna say, the casting for this lakorn was spot on esp with Dao and Nuk, which is probably why I'm not scoring this lower. Otherwise, this is not something I'd re-watch and not my cup of tea.
