This show made me so mad. It was a great beautiful story (very slow moving) and then it just ends abruptly. It's too many open ends. There are so many plot points that are not wrapped up.
You have
1. The Substitute teachers
2. Tian's Dad
3. Both leads parents relationship
4. Tian relationship with his mother
5. Sheng's relationship with his father
6. The overachiever boy and his insecurities
7. The English teacher

And that's just seven right off the top of my head. There's a few more that I'm too mad to remember at the moment. That is why I gave this such a low score. Those take away from the story. I'm very sure it was ended that way to set up for a second season. But I've seen plenty shows that do something like this and don't get a second season. I need Taiwan to do better. This is the second time they have disappointed me like this with a drama
