I like how the writers of the series made a heavy angst to lighter version of angst. Sometimes I think I'm watching a romantic comedy series.
The actors really improved a lot with their acting skills. War can really show the characters emotions through his eyes. The professionalism he showed during accident in the pool scene was really awesome. Yin really improved a lot. I was amazed.
Music also hits the right spot.
I'll be rewatching it again and again. Just seeing the leads smiling at each other makes me smile.
