This is everything you need in one drama.

I have read the original novel before, the novel is more like some flashbacks and short stories based on the author's real life and her love story between her and her husband Mr F (as in Frank). It was sweet and not so detailed. Then news came out saying they are going to do a drama-adaptation of the book, I was half-excited and half-worried.

For someone who watched more than 10 episodes per day, I can say this drama is good, its worth your time, it has the sweet, the pain, the sorrow, and the rainbow after the rain. However this drama has its sad elements, it sure made me cry but i think its still worth watching.

SPOILERS AHEAD：
The plot is just so perfect.
Maybe because the characters are based on real-life people, each of them have their unique personalities, their good side and bad side, none of the characters is perfect, but we can see character development throughout the drama.
Guan Chao is the brother every girl wanted, handsome, smart, loves his sister until the world's end, but he is always flirty with other girls, he has his own insecurities which he did not shared until near the end of the drama. He acts like he's okay to protect his loved ones-- Qiao Yi and their mom.
Qiao Yi is kind-hearted and sweet, but she has low self-esteem and does not express her feelings very well. She tends to hide her feelings from her friends and family very often and the show teaches us that sometimes its okay to ask for help, because there are people around you that loves you.
Yan Mo is smart, he's the kind of person that has everything planned, what to eat tomorrow, which chapters to study in the following week, which university to go to etc. But he is a loner, he too does not express his feelings very well, in a high self-esteem way, non-sociable and has a mean mouth. He and Qiao Yi are the type of couple that can hold grudges for years. Towards the end we could see how he opens up to people, to care for others and to accept social cues and respond to them.
Wu Yi is Qiao Yi's best friend, she is those who dares to love and dares to hate, she is like a durian, with sharp-pointy outer shell and slimy fruit on the inside. She is the opposite of Qiao Yi, who is stubborn, Wu Yi also has her insecurities and is afraid of change and stepping out the first step in everything. She also likes to runaway from her problems, literally running away from them instead of facing it and solving it.
Da Chuan is the best friend everybody wishes for, he will not hesitate to lend a helping hand. He is bold and gangster-looking but has a kind-heart that has a soft spot for animals. He is very sociable, he can be friends with anyone including your parents. But he is also hot-headed, he tends to loose his temper easily and that sometimes causes trouble. Da Chuan is the person that keeps the gang together, he apologizes when he is wrong, he forgives and he appreciates.

They did a really good job in including the main leads' family dynamics. Guan Chao and Qiao Yi's mom remarried to their stepfather, they showed the reaction of both child, and their process of accepting him. They show how their previous abusive bio dad affected them later in life, which is really sad. Another to add is Guan Chao and Qiao Yi's sibling relationship, they supported each other when needed, they are very very close, very well portrayed.
Yan Mo's parents were also divorced, they show how he has to cope with it, how his mom made effort to give the best to him, and how his cold personality was not a one-day thing.
Wu Yi came from a single-parent family where her mom is a busy businesswoman and both mother-daughter lack communication which results in a stranded relationship, its heartbreaking towards the end of the show.

Some say the drama was boring during the middle episodes, this is because during that few episodes, the gang is dealing with stuffs other than their love-life. Although love is a necessity (all kinds of love, not just the romantic kind), but there also other stuffs in life we need to handle, like career, friends, family, this drama included other hardships that the leads' faced to show that life does not always go the way we wanted it to be, even if we put in a 100% effort, we might still fail, and it take another 200% effort to stand up again, this is how life works!

Acting wise, all the leads fits into their character pretty well, crying scenes were good, especially Wu Yi's, and Guan Chao's about-to-cry face expression changes deserves some applause too. Yan Mo needs to have his feelings expressed through his eyes, gestures, body language which is not easy too. Qiao Yi's character there's a difference in acting, she was really shy and timid during high school where she avoided eye-contact, speaks in a very soft voice and often hunches when people talk to her. She experienced a change in university where she joined clubs and societies and you can see how the actress put in confidence elements in Qiao Yi, she is more matured and confident, although she still panics when she encountered Yan Mo again but you can see the change in acting, praises to the actress!

Overall its a good and addicting drama to watch, acting is good, chemistry between the leads are good too, the story plot and script is the best part of this drama. Character development throughout the drama. Not a very poor production team so the set was ok, kept it real and not over-the-top fancy. Rewatch value was lower because i don't want to go through the pain all over again, but youtube cuts are the go-tos, just rewatch the cuts will be enough hahaha.
