f(x) Amber's "boyish" selca has been getting attention lately.

On April 2nd, the star posted on me2day, "On rainy days~ I'm gonna stay home and play!" and uploaded the selca above. The photo shows the singer sporting a short haircut and wearing no make-up in a close-up for the camera. Amber seems to know that her charm comes from her unique tomboy style.

Fans wrote, "It's raining a lot outside, so have plenty of rest at home," "Unnie, you're so cute!" and "Were you mentioning B2ST's song?"
