The song playing is Against All Odds by Mariah Carey.
Never fall in love my friend, you see it doesnt pay. Even though it hurts so much, it happens every day. It starts out grand and ends in tears no matter what you do. You see my friend, I ought to know, I fell in love with you.
Love really isn't worth it. It was made only to make you cry. You will be happy one day, then the next day you want to die. The pain you feel is worse than ten thousand stabbing knives. You can go ahead and fall in love, but for me, I'd rather die.
Love is never kind or just. It knows no thing that's real. It was made up for the meek and foolish, and disguised as love indeed. No matter what you do, no matter what you say: love doesn't care about you. when you see it run away.
