I need help! I can't remember the name of a drama, and I don't remember if it was Korean or from another country. It is about a boy and a girl who meet in another country, and when they get back home they become really good friends. Then he starts dating her friend who is a ballerina, but she starts to get jealous of the friendship between the main guy and girl. The guy's dad also likes the first girl better so that doesn't help things. The boy finally realizes that he loves his friend and breaks up with the ballerina. Then the friend goes blind and wont accept help from anyone. I am starting to think that I dreamed this drama, but I remember it so clearly. Please help
