f(x)'s Luna greeted fans through her pictorial and behind-the-scenes clip for 'International bnt'!

During her interview with the magazine, Luna was asked what she regrets the most about 2014, and she shared, "I prepared for a long time, but I wasn't able to show a lot to fans... But I will work harder to show a bit more mature and better f(x) stage in 2015."

When asked what has changed the most since her debut, she replied, "My thighs... I like being honest. I normally like exercising, and as I spent all day dancing in the practice room since before my debut, muscles naturally formed... For a prettier [body] line, I maintain how I eat and exercise systematically, and I am consistently working on it."

Let's hope f(x) make a comeback soon!
