Best Time (2013)

Same actor obviously, but also generally two "feel good" dramas. My sunshine is a bit obvious and super slow - but so lovely I was just smiling to myself and downloaded the whole soundtrack! Best time has also a lot of slow moments and is a bit more sad but also very positive and sweet! Both dramas are set in Shanghai and show a very modern and trendy China (I totally want to move there now :) Bonus point- Best time offers alternative endings! (this way everybody is happy :>

love triangle is similar with a boss that has fallen in love with the FL. but the FL likes another guy all the way.

In the female lead is stuck between two male leads. in each of these dramas. In both dramas , there are alternative endings and the female lead ends up with each male lead based on the version you see. Both are in Chinese , I feel Best Time is the better one.

Best Time is the original series. If you want to know the original storyline of this special you must watch the series Best Time.

Same feel, same mix of business and romance, though the balance was much better in The Queen of SOP.
Both involve strong capable female lead, a caring male lead and a love triangle (unfortunately...)
Warning : Best Time's ending was extremely off-putting to me (and to a lot of other people as well I guess).
