Maybe I underestimated this film before

You can say that this drama detailed not very good, and some scene don't match the preview of the previous eps, and it's like forgot to add it in the next episode(part ding dang & teacher hao eps 21,preview ep 20)

But the feeling given is very full,,emotional ,warmheart ,, i enjoy it ,,make me cry and smile

At the beginning of the drama, I was a bit bored, but later on, the more exciting, the story is very realistic, about one chance to make up for past regrets, friendships,youth that we will always remember at that time,, the actions taken are very funny (light comedy) and unexpected and the dialogue is also very artistic, and the OST very nice




But i have some question to ask
1. What is chen tong secret? What he said to weixiao in last eps
2. ‎what is liu da zhi want to ask when he give concert ticket? Last
