In my eyes, this is a heartwarming love story, "slice of life" drama with independent, mature characters.
It is kind of slow-paced, letting us take part in the characters' backstories and personal developments.

The fact that there are no workplace drama, crazy scheming jealous other parties or over-controlling relatives, makes the story more believable and relatable.

Brief synopsis, as per my memory:
A chance encounter brings former couple Gui Xiao and Lu Yan Chen back in touch with each other. They fell in love in their middle school days, and tried maintaining a long-distance relationship when education and career paths separate them.
Can Gui Xiao, with a successful career within finance, and Lu Yan Chen, a special forces police officer in a different part of the country, overcome the emotional wounds from the breakup and rekindle their feelings, with the obstacle of geography and careers?

Some notes:
The soundtrack was fitting.

Acting was convincing. This really opened my eyes up for Tan Song Yun as an actress. She brings a very good energy and charm to her character. I sometimes found myself suddenly smiling by the sweet interactions between the two main leads.

What bothered me a little bit was that many of the episode endings seemed very abrupt (Viki).
