Personally, my fav couple is So Yi jung and Chu Ga eul. I keep thinking about them. specially that they didn't get a fair ending. It was sort of a loose end for me and I hate loose ends.  My second favourite :Lee Yoon-seung and Kim Na-na <3 <3 Thei chemistery is undeniable. Also, Tae-joon and Jai-hee from to the beautiful you. She really tried her best to be there for him. I didn't like the ending. I thought she was supposed to go see him at the competition. But she really changed him. You who came from the satrs, The leads had a lot of chemistery. They were funny and cute and they made me cry. Specially Do Min-joon when he was watching the vedio that Song-yi made for him T-T. It was sad and very meaningful. And of course I can't forget Hwan Tae-kyung and Go Mi-nam "Go Mi-neu". Lie to me Hyun Ki-joon and Kong Ah-jung

Who is your favourite?
