Me personally, I enjoy this drama from start to finish but that doesn't really make it a perfect (10/10) drama for me. There are a lot of things I like about this drama and other things I felt like this drama missed out on. So let's go over my thoughts.

What's in this drama:
* A boss & assistant relationship. FL is the boss and the ML is the assistant. This is an older female and younger male relationship
* Love triangle sort of exists in this drama but it's a tamed and controlled love triangle. Jiang Yue has a crush on her former boss Xu Ning, Jia Xin tries to help her get with her crush but eventually falls in love with her instead. This leads to Jiang Yue's feelings changed eventually to where she starts to like Jia Xin. All at the same time, Xu Ning ends up having feelings for Jiang Yue and Jia Xin's clingy and obsessed childhood friend Yan Ran has been chasing after Jia Xin since she was a little kid, hoping he would accept her feelings for him.
* Two other couples are featured in this drama: One couple showcase a misunderstanding which leads to hardship in their love while the other couple is just so darn sweet & cute.
* Heavily focuses on the company aspects aka Love Note App. Each ending showcases a love note advice from either the main or side characters.
* Minor villain in this drama. Appears very late in the drama and is only in a few episodes before being kicked out.

What I liked:
* Great chemistry between the leads & our cute & adorable side couple (Duo Xi & Qi Heng)
* OSTs in this drama are my favorite, especially the intro & ending songs. Added each one to my music playlist.
* Character development for everybody, from our main leads to our side characters who are our 2nd & 3rd couples.
* Love note advice at the end of each episode
* A satisfying and happy ending

What's I'm not a fan of
* Story was just average overall due to the plot being focus on the love note app and the company. I wanted to see more in-depth scenes about the backstory of our main leads. The drama showed some backstory but lacked the details and scenes for a viewer like me to understand the characters fully and to see the steady progress of overcoming personal struggles. Content was there for Jia Xin (mom and son relationship, & trauma from a close friend's motorcycle accident), & Jiang Yue (hardship with dad and the reason of not finding love).
* The handling of one of the side couple's misunderstandings: I don't wanna give too much away but I felt like it should've been more about the building of their relationship again instead of the instant "oh you still love me, let's be together again". I'm glad they're together again but I wanted to see a progress of this couple rebuilding their relationship, instead of acting like nothing bad ever happened between them.
* A bit too much clinginess and stalkerish actions.
* Filler episodes towards the end: I wasn't a fan how they introduce a so called "ex" and a minor villain, who only appeared for a short time for like 5 episodes. What's worse, the writers tried to make you sympathized with the villain. No thanks!

Liked I said before, I enjoyed it. Even with all of the stuff that I had some issues with, it was still an easy watch for me. Keep in mind, this may or may not be a drama for you but it's up to you now you have an idea on what to expect.
