WATCH: All eyes were on the BTS star as Ruud attempted to win his first match in Seoul on Thursday.


Good morning, BTS stans! Your man Jin of BTS was watching tennis today.

But you already knew that.

For those who don’t: the Eugene Korea Open Tennis Championships was infused with a whopping dose of K-Pop energy on Thursday as Kim Seok-jin, known affectionately as "Jin" by his millions of fans, watched world No. 2 Casper Ruud make his Seoul debut against Nicolas Jarry.

While the Norwegian ultimately solved Jarry in three sets, an army's worth of eyes were on the BTS star, who was seen watching and taking pictures and video from the stands.

Not even a mask could hide his face from the keen eyes behind the camera!

As some fans pointed out, Ruud could have tagged Jin onto the court if he was feeling especially overwhelmed by the Chilean in the final set:

Might Casper count on support from Suga, J-Hope, RM, Jimin, V, and/or Jungkook ahead of his next match against Yoshihito Nishioka?
