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 :>
