EXO's Kai and f(x)'s Krystal have reportedly split. The two decided to part ways after a year of relationship.

SM Entertainment, who manages both the celebrities, confirmed the break-up news. The agency said in a statement: "It's true that they've decided to part ways."

The two apparently ended the relationship due to their busy schedules. A source close to the couple told Soompi: "It is true that the two have broken up. They've been unable to meet often because of their busy schedules. I don't know the exact reason for their breakup but I think they've both decided to focus on their careers."

Kai and Krystal met in 2007 as trainees, and their romantic relationship reportedly began last spring. SM Entertainment stated at the time: "They began having feelings for each other earlier this year after being close friends for years."

An insider had shared: "The two know that they are similar: looks, personality, taste in music, fashion taste, and hobbies. It was inevitable that they became lovers."
