Love, for some people, might be tough, but for others, it might be as sweet as candies. We always see 'forever love', 'love you forever', etc. everywhere, printed on the cups, cards, pillow, you name it. But, how many love will last Forever? Will everyone have a happily ever after ending as in Sleeping Beauty or Cinderella?
Love is complicated. I agree. It can make you feel like you're the best in the world, it can also makes you feel like you're even worst and useless than a trash. But, people still love the feelings of being in love. There are bitter and sweet, just like chocolate, bitter and sweet, but still people love chocolate.
However, love really can change a whole lot of people, from physical to mental, or even from good to bad. Me, personally, love the feelings of being in love. Sometimes, it gives me bad time too. But, overall, it's sweet.. :)
