After meeting and falling in love on the set of "Blood," co-stars Ahn Jae Hyun and Goo Hye Sun have finally tied the knot, but in a not-so-orthodox manner. 

On May 21, the couple officially submitted their marriage resistration documents, but instead of having an all-out ceremony and reception, the two decided to give back to the community instead. 

According to HellpKpop, a day after registering their marriage, the two went to the children's wing of Severance Hospital in Seoul, where they donated the money.

Rather than wearing a wedding dress and tuxedo, the two showed up in more casual clothing, where the medical team expressed their gratitude and thanks for the couple's generosity. 

The names of the newlyweds were also printed on a sign and placed in one of the treatment rooms as  way to thank the couple for their donation. 

The money will be used for disease research and rest facilities for children who are patients. 

"We want to have a worthwhile life where we help others, so we decided to make our thoughts reality through our wedding," the couple stated. "We would like to give hope and strength to young patients who are fighting disease and illness."
