While The Fault in Our Stars trailer is uplifting, it might make you cry. Based on the YA novel by John Green, the story involves a young girl, played by Shailene Woodley, who has been diagnosed with cancer. She meets a young boy whose cancer is in remission, played by Ansel Elgort. The girl tries to keep her emotional distance but the boy is head over heels for her and gently loves her until she can't help but fall in love with him, too. Then our tears begin to fall. The end.
