Like many others, I only watched this for PeteKao after seeing Dark Blue Kiss. GMMTV uploaded scenes of only PeteKao to YouTube lol. They know their audience. I must say I was incredibly bored of the beginning because the story and the characters were incredibly juvenile. The directing is also worse than its sequel as there are a lot of awkward beats while there are none in DBK. The actors also seem to gel a lot better in DBK, although the chemistry between Pete and Kao is still great and no one called Kao the wife since they've only started dating. That's a plus for me. While I like seeing characters evolving throughout a series, due to how bad the first half of the show, I'd just recommend you watch only part 3 of the PeteKao videos. They are very sweet with each other while they're "not dating" and I love how Pete made the argument for them dating when his father confronted them.

There are some minor consistency issues like how Pete and Kao's clothes were pretty much dry after playing in the pool.
