I'm looking for Kdramas with a more aggressive flirty FL that teases the ML who is a bit shy or inexperienced in relationships. Where the ML has some fun cute reactions to these teases by the FL.  

It's Okay, That's Love he's not shy, just a bit more reserved

The Master's Sun same

Jealousy Incarnate  he thinks he's too good for her, but he also has deep feelings of inadequacy underneath.

All with Gong Hyo Jin. She's really good at playing the shameless girl.

Oh My Ghost a thai version exists

You Are My Heartbeat a chinese version exists

Backstreet Rookie - FL is quite aggressive, stromg, badass... like a beast. ML is more reserved... like a little bunny. Bunny vs beast... it is clear, who gonna win. :)

I'm Not a Robot - FL is maybe not that much flirty, but she is cheereful and ML inexperienced because of his illness (he has allergy to humans and can't touch them), that brings many funny situations.

Goblin - FL is very flirty. ML is reserved and quite lonely. If you don't mind big age gap between them, it is great drama.
