Is This Love? (Elnella)

I was the girl who believes that love is just a Misery until I realized that I was inlove with my bestfriend we were bestfriends since we were kids and I really wanna say I love him but maybe I cant cause if I will maybe he wont forgive me kasi promise namin na magiging bestfriends lang kami kahit anong mangyari. I dont know what to do?
