My oversimplified review
STORY: Interesting allergy to tears, being a person who typically does not like things like that, it fit well with the plot. Really enjoyed how capable both the male and female lead were. Loved the business/workplace setting. Side couple was also interesting to follow and did not interfere with the plot.
EXECUTION: The chemistry between Leo Luo and Bai Lu was phenomenal in Love is Sweet (their personalities off camera also work well together). Great costume design, loved the outfits of Jiang Jun. Music worked well with what was on screen, my favorite being A Love Song for You. Nice humor throughout.
OVERALL: Watch for the chemistry between the two main characters, the office setting, and a super sweet office and rivalry love story.
