I was kind of unsure if I want to watch this series... this huge age gap and the daughter... I didn't know if they'll be able to pull it off...
I had no reasons to worry!
This is not your typical BL drama. It might be sweet and cute but the relationship itself is quite unusual.
Drama concentrate mostly on Shi Yi Jie and Fei Sheng Zhe relationship. There is a "side couple" but they have hardly any time to develop their relationship, from my perspective their job is mostly to ease some tension when problems show up and bring some laugh as they tend to behave quite funny and chaotically .
FSZ is a warm person, very loving and considerate but quite unconfident and scared as he went thru some hard moments in the past.
SYJ is quite a lost person... messy, unorganized and very lonely. He loves his daughter but he doesn't know how to be a father (there is another reason to his behavior, watch if u want to know :P ) and so he tends to bury himself under the mountain of books.
SYJ somehow meets FSZ that shows him how lonely and lost he was all this time, FSZ points out for him his faults and mistakes while showering him with warmth...
What I love is that SYJ doesn't need anyone to tell him about his own feelings and he doesn't need no-ones assurance, when he finds out he wants this boy to stay by his side he is not shy, he faces FSZ and express his feelings in the honest and straightforward way. He knows how world works but he want to be brave for the one he loves and he doesn't want to hide, he wants a normal relationship.
There are pros and cons to this relationship and the age gap (12 years), SYJ has more experience in life situations and he doesn't get lost or confused, he knows what is needed in the stable relationship (I always have problem with this in dramas as characters tends to assume a lot of things, easy get swayed by others or just don't open their mouth to ask questions that would make their life easier and would fix mont of the problems), SYJ wouldn't let anything and anyone go in-between of them, he fixes avery problem systematically so FSZ would not feel hurt and so their relationship can progress.
FSZ ... what to say? He my looks like an adult and he is quite a responsible boy but when they meet he is only 19... VERY YOUNG... he is scared and he makes mistakes as he doesn't know how to proceed with this relationship. Everything is new to him and he's just a young unexperienced man... He is so lucky that he met SYJ that is patient enough to teach him... If this was relationship between two 19 y.o. guys they would have broken up long time ago.

I fully recommend this series as the topics it touches (marriage, trust, children, problems growing up as a gay, hard childhood) are very important and I think we should have more dramas/movies like this.
Yes this series is too short to give us in-depth exposure of this topics but the way it's touching them here is very well done, brief but with a taste. All I could wish fore is more time for them to explore...

Well written and well directed series! Good acting ! Even You You was such a good girl!!!

It was such a pleased experience I'm sure I'll be back for more!
