I really loved this. I first hesitated if I was going watch this coz I didn't like Kanompang and Non in season 2. But in this series, I learned to love them (not fully but I did)

1. I hated KoiDao scenes that I had to skip all their parts but I didn't feel like I missed any part of the series. Their parts were ALL OVER THE PLACE. You can enjoy the series without them coz they're like in the same university but felt like they didn't connect to the rest of the story. They could've replaced KoiDao part with Boss which brings to my 2nd point.
2. Boss' character had sooo much potential. He genuinely cared about people around him and he had good intentions, just like Non. But the difference is that Non gets people's attention, people listen to Non and appreciates him while Boss is being ignored and no one sees his effort and intentions 'til it just turned to hatred that ate him. It became toxic that he forgot who he really is. It would've been great if Boss had character development and people finally understand his intentions instead of adding random Koi Dao scenes.
3. This series covered real life and more interesting issues like Drugs, Prostitution (sort of), domestic violence, LGBTQ+ family and HIV awareness

....might add some more later.
