We all know that Miss Universe 2015, the stunning Pia Wurtzbach, is (or was) an avid fan of Super Junior's Siwon. At least that's what we gather from reading her past tweets, where she fangirls to her heart's desire over the handsome singer.

People were wondering--the staff at AKP included--how Siwon would respond, and lo and behold, he uploaded a post on his Instagram recently congratulating Wurtzbach on her winning Miss Universe 2015. 

His post reads, "Pia Alonzo Wurtzbach :) Heartfelt Congratulations on your Miss Universe 2015 Award, and please be my guest for next SUPERSHOW! Looking forward to seeing you shining the world :^)" 

And Wurtzbach responded to Siwon's response, with a comment on his Instagram post. She commented, "Wow thank you :D Really appreciate it! anyong haseyo!" 

Awww, how cute. Maybe the two will get to meet in person one day!
