Love me if you dare - Psycological
Le Jun Kai - very short but good
Sealed with a kiss - not everyones idea of a good show but if you go into not taking the show literally then it's enjoyable
Lady & Liar/Too Late to Say i Love You - not historical but set in the early period.
The Whirlwind girl - i enjoyed it, its a martial arts romance
Cambrian Period - just watched the intro and was intrigued ... i thoroughly enjoyed it.
Beloved enemy - based on a BL book but there is no BL in it but you can feel the chemistry.
Some to get you going.
