I came up w a list it has light plot and mood lifting dramas. I am watching Go princess go and so far I loved it! Episodes are short they are of 21 mins.
Go princess go, perfect couple, my heroic husband (watched this till ep 9), Cinderella chef, the eternal love, Love through a millennium, Rooftop prince, romance to tiger and rose, general's lady, the cupid of chou dynasty, love is sweet
If you know any similar kind of drama then tell me. I don't like those dramas where couple are so much in love and all cheesy, lovely etc. I feel uncomfortable watching those.
