Pure 19 (daily drama is 167 ep 25-30 minute originally , but the eng sub version is edited into 122 and is about 45 min each , is one of my favorites family dramas.)
Family's Honor (Two main leads and their siblings all had great love stories.)
Golden Bride
I Believe in Love (the two older sibling's love stories were boring to me but the two younger sisters love stories are cute.)
My Husband Got A Family
House Of Bluebird
I also loved Life Is Beautiful is really good.
