A U.S. Marine currently on deployment shocked his sister by making a surprise appearance at her May 18 wedding in Charlotte, North Carolina. The touching reunion caught on video was going viral on Thursday.

Daniel Atwood apparently tricked his sister, Sarah, with a letter informing her that he wouldn’t be able to get leave to attend the wedding. The news was devastating to Sarah, who considers her brother to be her best friend. She says she cried the night before her wedding because she thought her brother was going to miss her big day.

Little did she know, it was all a ruse to make the moment even more special. Watch the heartwarming video here:
