Cold and unapproachable female leads

Please recommend me a drama that has cold and approachable female lead  but sweet when she’s around around the male lead! I like the male lead to be a sweet guy that brings out the best side of her! 

This drama are the ones that i have seen and has this type of female leads

- Angel’s Last Mission

- Yongbal

• That fool
• Takane no Hana
• Strongest deliveryman
• Innocent guy

That winter the wind blows
