Last week, Jin was noticed at the Korea Open 2022 tennis tournament, watching the match of Casper Ruud. He came unannounced, hid behind a mask and a hat, and left right after the end of the match. Jin didn't even post anything regarding it on social media.

However, just him being in the audience created a fuss on the Internet. More than 1 million people viewed a 10-second-long close-up with the artist in just 2 hours. The sports media emphasized how a single video with him got 20 times more views than an average tennis-related post. Most of the major global tennis-focused media outlets made multiple posts about Jin's attendance. The commentator of the match kept coming back to Jin sitting on the center court and named him a 'Superstar in the stands.' After the match, Casper Ruud said that he was proud to know that an artist like Jin was interested in tennis. A few other tennis stars commented on Jin's visit as well. And one of them even invited Jin to all of his future matches!

The fans of tennis players didn't expect to see such a craze around Korea Open 2022 that Jin's appearance caused. One of the media outlets even quoted a fan, saying that the artist gave more promotion to the event than the ATP Tour did. The articles about Jin trended across all of the Korean sports media websites.

Naver Sports released a special article mentioning Jin's attendance on October 2nd. It's titled "Korea Open’s record-breaking success in tennis craze."

The article talks about the current popularity of tennis in South Korea. It gives a detailed insight into the ticket sales for the semi-finals and finals in South Korea throughout the last two decades. It also explains why tennis has become more popular among the younger generation, following the steps of golf, which has been a common way to spend the weekend for millions of Koreans for many years. The number of indoor tennis courts is rapidly increasing as more and more people get into this kind of sport.

A whole paragraph of the article is dedicated to the fuss Jin created at the latest Korea Open 2022 match of Casper Ruud vs. Nicolas Jarry. It states:

"On the 29th of last month, Jin (real name Kim Seokjin) of BTS, a singer who enjoys worldwide popularity, watched the round of 16 match between Casper Ruud and Nicolas Jarry (111th, Chile) and it became a hot topic. After winning the match, Ruud replied, "I am thrilled as a tennis player that Jin likes tennis." As a result of such a high interest, sports brands such as FILA, Dunlop, and Le Coq, as well as various brands such as Lotte Chilsung Beverage, Goobne Chicken, Papa John's, and Subway participated in the event as sponsors."

The popularity of Jin is truly incredible since he is able to attract so much attention to any sphere just by showing up to the event!
