The hottest kiss i have seen happened in the second episode of Love, now (Taiwan) avec George Hu. It is his honeymoon and the bride enters in the shower while he is taking a shower and kisses him. Unfortunately the drama beggins well but it is too long for me and after  i have skipped a lot. The chemistry was great but there sere too much dramatic events for my taste. 

You are my glory - chinese

though you need to get through the first 20 some episodes to get to the best parts ..hehe

 Heavenly6:
* Obsessed.... Song Seung Hyun and the lead female have some amazing love scenes and kissing 

* Servant.... Beautiful love story between a male servant and the woman she loves plus some great love scenes 

both are great!!! (obsessed is amazing movie) but servant has different name here Bang Ja Chronicles 

 Azzuritis:
Cruel City- pretty steamy,

GREATEST drama and even one steamy scene of them was better then most of romance dramas )))))

I dont know if anyone has recommended to you yet but this drama is so good: You Are My Glory
