I thought I'd weigh into the conversation as a veteran lakorn-watcher.
The thing I love about lakorns is that even though the majority of them aren't very well-made, they have so much heart. They leave you with happy warm fuzzies after the final episode.

That's the best thing about this lakorn.

Now, is any drama from any country perfect? No. There's always something that the writers messed up on, or that one bad actor, or that annoying music, etc. This lakorn is far from perfect. However, the big heart it has combined with some fantastic acting from the leads more than makes up for that stupid hacking storyline (y'all know the one).

I normally don't watch Mark Prin. I didn't like him much in Kluen Cheewit (I know, the forbidden words-- I didn't love Kluen Cheewit), maybe because of his acting or maybe because of the directing. I was a little hesitant to watch this one because of that. However, I must say that Mark and Mew made this lakorn. It's rare to see such solid, convincing acting in a lakorn combined with such natural chemistry. Both of their acting has improved a ton since their newbie days and it shows. Mew managed to pull off her character without being annoying at all. Also, the skinship scenes were... ahem... very enjoyable to watch.

I also love how the writers treated the leads' story. They didn't have any annoying misunderstandings or miscommunications. I loved that Mark had to work to earn his place in Mew's life again. He had to change for their relationship to actually work. I loved that Mew forgave him relatively quickly. Their romance is portrayed in a mature, believable way as Mark slowly realizes his love for Mew.

I didn't like the hacking storyline. It was dumb and felt out of place. I also disliked the fact that they tried to convince us that Mark liked Mew when they were in school. Um... doesn't that undermine the entire plot here? These are minor flaws, though.

I highly recommend this lakorn. I'll definitely re-watch it.
