The latest post, shared on Instiz in March, showed the EXO and Girl's Day member both wearing similar pairs of sneakers with black and white hearts.
Son Heung-min, who plays for Bayer Leverkusen in the Bundesliga, is dating Min-ah of K-pop band Girls Day.
hosted by NU'EST member Aron, who she is also good friends with.
During a part of the show, Amber was asked "what was the one rumor that was pleasing to hear even though it wasn't true?
What about a rumor that wrongfully accused you of something, or that was unfair?
" "I think this can go either way, I think it's for both," Amber began.
"It's funny when I hear that I'm dating so and so, but it's not a guy. It's so funny." She then told a story about when rumors mistook her for a man in pictures with 4Minute's Hyun A, during Hyun A's Troublemaker project duo promotions.
Because of Amber's fashion sense and the fact that she was wearing a hat in the picture, she was mistaken for Hyun A's date rather than a friend.
"The funny thing is, I'm dating more girls than guys, which is [funny], cause you know, I'm close with you, [BTOB's] Peniel, [C-CLOWN's] Rome.
But when I'm with guys, nothing is like I'm dating Aron or Peniel, it's like I'm dating Krystal or Minah, and it's cute." But not everything about the rumors are funny to the f(x) singer.
"I don't like it because it puts my friends in a very awkward situation, but I also like it because it's kind of, oh...
People say that I look like a boyfriend, that I can take care of people.
I like that because it shows I take care of my friends.
