JYJ kicked off “2015 JYJ Membership Week” on Monday at Seoul Art Gallery, an annual event in which the K-pop boy group interacts with its fans.

At this year’s edition, a photo exhibition is underway, featuring rare photos of JYJ members and a charity auction is also planned.

JYJ members Park Yoo-chun and Kim Jun-su showed up on the first day of the event.

“The photos remind us of the good memories of the past,” Park said. “We hope our fans can also share those special memories once again through the photo exhibition.”

The event, which will run through Aug. 30, is expected to attract around 20,000 visitors, including about 3,000 Japanese fans, C-jeS Entertainment said.
