It was a rocky start for me. Four things almost made me give up early on.
1) Joseph Zeng in the lead as Lu Zhao Yi - I wasn't too sure. He seemed inordinately young, not only to tackle the part of the male lead, but he's supposedly the company president? I put aside my pre-conceived notions and settled in and he was absolutely one of the high points of the show.
2) Liang Jie as FL Ye Shi Lan - I found her character to be very unlikeable at the beginning. Cold, hard - thankfully that didn't last long.
3) She's a pediatrician but she works as his assistant?! Wow, I SERIOUSLY had to suspend disbelief here.
4) Typical Chinese slow-moving script. I felt that it struggled to find its footing in the beginning, but once the two leads started interacting, all was forgiven.

However, once I got involved with these characters (and the script, for the most part), I was in love. And there were SO many reasons why:
1) The main couple was just so darn cute. Really, I really appreciated the script writers here, in that they showed a natural relationship progression. We got the initial misunderstanding (which was taken care of quickly), which was followed by being able to watch them become friends, and then more. I really appreciated that we knew they liked each other before they did, that made it even more fun. There was a lot of heart and a lot of humor with these two. I felt that their chemistry was realistic and amazing. Good kisses and not a lot of push and pull between the two.
2) Zhou Zi Han as Kevin and Li Lin Fei as Yao Jia Jia - as friends of the main couple they were supportive and likeable. But once they got involved with one another? Oh my gosh, I loved their screen time as well. Even though his facial expression never changed much, you could feel his emotions. He had a kind of secret hobby that brought him into her sphere, thankfully. And her? She was the sweetest, most supportive friend, and she was just precious, with her cute hairstyles and that beautiful smile. I loved watching these two get to know each other, again developing a friendship first, before moving forward.
3) I smiled through most of this. It was very low angst, which I always appreciate.
There were just as many things that this show DIDN'T have which made me like it:
1) No evil ex-girlfriend trying to get back with him.
2) No evil parents trying to break them up.
3) No constant making up/breaking up/misunderstandings. Let's be honest, most romances have a certain amount of buildup, but then they spend more time apart than together. Not here. There was only one "fake" break up, and it kind of made sense and didn't go on forever.
4) No time jumps.

So, I'd say, if you want a feel-good show, with two healthy relationships and a lot of heart, you really should try this one.
