Dramas where the main girl is introverted

Hello! Im looking for dramas & movies where the girl has  introverted personality. Like in japan movie close range love, id like if she is shy or introverted. I watched 2 eps of just between lovers and i can say that it also has a girl who doesnt open up easily to others. So in precise i need a drama with the girl shy/introverted/refuses to open up to others. Im tired of seeing same kinda loud female leads. So im looking for a change..:)

Thanks in advance..:)

My Sunshine - She is pretty introverted and quiet, also has a hard time opening up to people.

Autumn's Concerto - Another introverted person the drama doesn't really focus on it though, but you can tell by the way she interacts with people.

Love O2O - This one has a group of friends and is somewhat popular, but her core behaviour is timid, introverted and cool. 

The happy loner has a really introvert female lead and a cute, endearing male lead. Just two episodes
