It's rare for idols to have public relationships, but B2ST's Junhyung and Kara's Goo Hara have been quite the exception.
But the relationship hasn't been easy for everyone.
Bandmate Yoseob admits that he felt resentful towards Junhyung when the pair were first outed in 2011 as he worried it would cause problems for the future of the group.
Speaking on The Beatles Code 2, he said: "I was resentful for some things, and I suffered. On the day the news was released, I checked my phone at least once every hour.
"But the relationship didn't go public on his own will."
The 23-year-old singer went on to reveal that on the day they all gathered to talk about the situation.
He added: "I told him, 'This relationship has to last for a long time... Now [that the news is out] it's up to you to make your relationship lovely and beautiful'."
