Park Kyung said he wouldn't be able to accept his girlfriend having male friends.
He was a guest on JTBC's 'The Romance'. During the show, he was asked if he could understand if his girlfriend had male friends, and he said, "It's impossible." He said, "If I meet him, I'd tell him that I heard a lot about him. Afterward, I'd ask my friend not to see him."
Actor Kim Ji Suk, who was also on the show, said the opposite.
That's toxic. If your significant other isn't allowing you to have friends of the opposite sex for petty reasons such as "it's impossible" save yourself the time, money, and effort and leave them. You don't want to be the one that looks like a clown.
