Wow, so all you needs are ROMANCE and KISSES. Don't watch this drama, just watch K-Drama. LOL
You watched 1st episode only and stated that FL is too childish and it was boring. Why don't you just keep watch it until the last episode and make your opinion? It's not fair you judge this drama but you just watched one episode. The FL is childish because that was her role, being overprotected by her mother.
