Mr. Best Man, Please Give Me Your Advice for the Rest of My Life.

Lu Shian, the youngest partner of an international law firm, was forced to team up with the bridesmaid Wen Shuning at a small wedding. Ten minutes later, he was hit by her tired comment. Wen Shuning is a jewelry appraiser and is most wary of people in high positions disguising control as favor; Lu Shian is used to arranging answers for everyone. A dispute over the inheritance of a time-honored jewelry brand brought them together, and also taught him to ask "what do you want" first in love.
