Loved every minute of this little gem.

STORY
I absolutely adored the fact that we knew beforehand that the main couple would end up together, it makes everything easier and more mature. It's basically the story of "how we met in high school and ended up getting married". The process is amazing, their infallible bound is enviable. I got butterflies when they did and wanted to cry when they did. This is one of the purest love stories I've ever seen, it's not only a first love or a high school puppy love, you get the feeling that the other is the only person they will ever love. The fact that it's actually based on the author's real love story with her husband makes it even more enjoyable. It's an extract from QiaoYi's novel I don't Like this world, I only like you and I think it sums up perfectly their relationship:
"Come to think of it, when I decided to break off our friendship I didn’t quarrel with him, and when we amended our relationship I didn’t cry. When we decided to be together he didn’t confess to me, and when we decided to marry he didn’t officially propose to me– everything just happened naturally on its own accord… It was as though both of us knew that these events would happen, and that both of us were simply waiting for the right time to arrive."

CAST/ACTING
I wasn't sure at first but I loved every character and their depiction.
There are three couples and I can assure you, you will love each one of them.
The actors did an amazing job, the chemistry is great, the kisses too. Loved the dynamic of the cast.
Special shoutout to the parents, extremely supportive and caring. The relationships were perfectly written, parents-children, brother-sisters, friends, lovers.
