What is the background behind the love affair rumors between Hee-chul (SUPER JUNIOR) and MITHRA JIN of ”EPIK HIGH”? = ”20th century hit song”

Hee-chul, a member of the group "SUPER JUNIOR," revealed an episode that was shrouded in same-sex love affair rumors with MITHRA JIN of "EPIK HIGH."
On the 7th, the 255th episode of KBS Joy's "20th Century Hit Songs" aired, with the theme "I Heard It Through the Grass! Singers Who Had a Loose Rumor" and asked singers who suffered from rumours of that era.
The show also featured songs by singers who have been the subject of constant love affair rumors since their debut, such as "Missing" by "Fly To The Sky."
MIJOO (LOVELYZ) said, "Even on variety shows, the two of them acted in a way that was misleading, which only fueled the rumors."
In a past variety show, Brian called Fany his "wife," to which Fany responded, "I'm the male," and Brian introduced Fany as his "husband" again.
Fany also said, "When Brian had to go to America for his second album promotions due to visa issues, his father came to pick him up and said he was against Brian's singing career.
He revealed that this episode, in which Brian and Fany said, "Please don't separate us," was the group's biggest crisis, and that this is when the rumor started.
Another example of a same-sex scandal is the case of Super Junior's Hee-chul and EPIK HIGH's MITHRA.
The Love Affair rumours with JIN were mentioned. Hee-chul said, "At some point, MITHRA JIN started to talk about 'EPIK'.
"I was in a bad mood because I kept it a secret from the members of 'HIGH' and contacted them secretly," he said.
Jin's car was so comfortable that I often sat in the passenger seat with him, and eventually I traded in for the same car," he said, explaining the circumstances that made it inevitable for the rumor to emerge.
In response, MIJOO asked, "Which one was the male?", making the studio burst into laughter. In addition, the famous singer's eight-year-old secret that should never have been revealed
