Like:
+ First of all; watch the ending scenes! They are important and fun.
+ I didn't expect such serious topics, but was positively surprised! They deal with realistic problems in a realistic and authentic way and which episode I fell more and more in love with each character!
+ The dentist team is so funny, lovely and heartwarming, I can't! They are all so so cute. T_T
+ The male leads are totally different, but have a great chemistry. I personally loved their kisses! :x
+ Loved the little habits they developed.
+ The couples are all so lovely and cute. I didn't watch a lot of shows yet, where there were so many couples, so I am not annoyed by it yet. I liked it. (- but it would have been nice to see more from Alex and RJ. RJ is such a cutie!
+ The OST is crazy good! Love love love it!!
+ Pacing was fine! Personally I would have liked the last conflict a little less dragged, but that's just for me, because I'm such an impatient person. I totally understand why they choosed this pace, so it's not really a critical point. And all the other conflicts get solved in a really nice pace! I've never felt bored or frustrated!
+ I got really teary towards the end because after watching them for such a long time (I normally watch dramas which are way shorter) it just felt like I have to say goodbye to some good friends. T_T

Room for improvement:
- Like I said, I would have appreciated it to see more from RJ and Alex. Geez. RJ stole my heart right away. T_T
- The last conflict felt both rushed and dragged. Dragged, because they spent much time to show how Bai Lang feels about it, but rushed because it didn't got the proper resolution on screen, which would have been nice.

Overall I am satisfied and happy with this drama! I would totally recommend it. It's a nice combination out of humour and serious themes. The balance is great and the transition from being a funny, shallow show into a more serious tone was great! While we're getting to know the characters better with each episode, the tone changes and we see under the surface. I really liked it.

I started the show with absolutely zero expectations (because it was my first (well, technically second, but I dropped the very first one) taiwanese drama, after I am slowly running out of k- and j- BL dramas I wanna watch :D) and I am so so happy that I liked the show so much. The story sounds so hilarious and funny, but the show gave me a lot more than just a few laughter. I really like each character and it would be so cool to see more of them!
