Drama with shy female lead

So far in all of the k dramas I have watched have a female lead who has an open personality. While I have come to adore and appreciate just about all of them I would like to watch more k-dramas with a female lead who is more shy and introverted and has a problem standing up for herself but comes to learn to do so. I am not particularly picky about what genre it should be. Though it should have romance. Whether the romance is the main or sub plot isn’t so important to me.

K-Drama with a protagonist with a very sweet or shy personality? Opposite protagonists as personalities?

Good morning! Yes I’m always ahah this time I was wondering if … Do you know k-dramas with a very sweet protagonist or a shy personality? A drama with sweet tones and not tired! I do not dislike the cheabol protagonists or a particular character (which do not fall into boredom or the stereotype), or who may have completely opposite personalities of each other. I’ve already seen Goong, Boys over Flower, Playful Kiss, Fated to love you, Coffee Prince.
