Shy female lead

I'm looking for dramas with a shy female lead who doesn't like talking much. But not because something happened to her in the past. It's just her character is like this. Any tips?

So a naturally and inherently introverted FL... and not one who was bullied, abandoned or had trauma thus they became itroverted?

• Kimi no todoke - her introvertedness lead to her being in rumors and then people dont talk to her
• God of study - not really introverted but she does seem to be a cautious person more because it is her personality rather than it is because of her circumstance
• Last Match / Final Game - very old korean drama
• 9 seconds eternal time - drama special
• Snow white / Taste Sweet Love
• Personal Taste 
• Nobuta wo produce - old japanese drama, thus i am not sure if the FL didnt have trauma in her past, but she is probably one of the most introverted character in dramaland
• Ode to Joy - one of the characters of the drama which revokves around 5 women
•
