This show is very 2005 kdrama like, especially the first half. (The Taiwanese flavor does not feel very strong.) In those ancient classics though the final 20-40% always tends to be very makjangish with absolutely insane Brazil soap plots. Luckily in this one the crazy is toned down a lot, so while they set up quite a few of those, they fizzled out every time, the drama does not even feature a breakup. The love triangle starts out as the very annoying friendly `ge` type, but discounting one (or two) three way handgrabs, it's far more tolerable than what you would normally see in a drama of its ilk.
The romance & the main characters are super juvenile as is common in this genre, though 28? yo virgins acting like preteens is understandably not going to be everyone's cup of tea..

Overall this has been solid entertainment for me, though it does get a bit draggy near the finale. (the plot has some really stupid things in it too, like the gangster's redemption ark, I mean what to fork was that?)

The repeated anime dancing is so silly that I could just not look away, even after seeing it 20+ times.
