a person who you will easily fall in love with, you may not know it at first but when you do it’ll hit you hard. You’ll fall for his amazing smile that lights up a room, or his laugh that makes your heart melt. Ky is a sweetheart and always an amazing boy to talk to. You wish he would fall in love with you because you’re madly in love with him.
