Drama with Quiet but not shy FL.

I would like to see a drama with a FL who is quiet but isn't considered weak.

Someone who is indifferent, and rarely talks to anyone, but opens up to the ML or her love interest.

To be honest, it doesn't have to be romance.

It can even be an anime.

Country of origin doesn't matter.

Release date also doesn't matter.

Thanks in advance :)

My mister, FL is not shy at all, she's quiet, cold and very tough/strong and independent and doesnt talk to anyone but she slowly opens up to ML. it's a really good story

1. Better Man (one of the F leads)
2. When a Snail Falls in Love 
3. The Story of Ming Lan 
4. Story of Yanxi Palace 
5. Find Yourself 
6. Across the Ocean to See You +1
7. Signal 
8. Seo Yeong, My Daughter 
9. Encounter 
10. After The Rain 

Flower Boy Next Door  (I think the FL fits the bill perfectly)

My Father is Strange  (does not fit the criteria exactly, the middle daughter-she is not indifferent & is part of a big family so she has to talk, but I liked her quietness & sweetness and I loved how the idol actor fell in love with her because of those qualities)
