JYJ’s Park Yu-chun and his bride-to-be Hwang Ha-na visited a local dog shelter and assisted volunteers.

Hwang shared the moment via her Instagram account Sunday, posting a video and pictures of Park and the dogs.

“It was the first time that I went to the dog shelter with Park. Thank you so much!” Hwang wrote in the caption.

Park put on a baseball cap and a mask in the pictures. Another photo shows him working hard to help volunteers at the shelter.

“We should visit some other shelters next week,” Hwang said.

Park and Hwang are reportedly scheduled to tie the knot on Sept. 10.
