What a difference a year makes.

On Friday, K-pop singer Se7en revealed he will be holding his first fan meeting in Japan in two years in Tokyo on July 7. Entitled Thank You SE7EN, the appearance will be the vocalist's first in the neighboring nation since completing his mandatory military service in the South Korean army back in December.

Se7en, who will reportedly make two appearances in Tokyo that day, has kept a fairly low profile since being discharged. Yet, his time in the army was not without its share of controversy.

Se7en, along with Sangchu of the group Mighty Mouth, was forced to serve a 10-day sentence in military jail, after a camera crew from the news program "Scene 21" caught them pair entering a massage parlor known for providing erotic services after curfew, back in June. The "Scene 21" footage rocked the South Korean Defense Media Agency, eventually leading to the elimination of the PR agency's Promotional Support Brigade.

Se7en is currently preparing for his return to the stage in an 11-week run of the musical "Elizabeth," opening June 13 at Seoul's Hannamdong's Blue Square Samsung Electronics Hall.

On Wednesday, he took to Instagram to thank his supporters for their generous gifts while he is in rehearsals for the show.

“Thank you so much for the coffee and food,” Se7en wrote.

Fan Sumcia Chan replied to the singer's post with a positive message.

“Be strong and eat well,” she wrote on Wednesday.

Se7en booster Kimberli also added her words of support.

“You deserve it," she wrote. "You’re the best."
