EXO's D.O. has been spotted with blonde hair for the first time since his debut.

A couple of photos of D.O. dining at a restaurant with acquaintances, including actor Kim Woo Bin, recently began circulating online. What threw fans into a frenzy was the EXO member's hair - shortly cropped and pale blonde - a look that the idol has never shown before. 

Fans wondered if D.O. had gone blonde for a new role in a series or a film, or if his transformation is for his solo comeback, expected to take place some time in July. 

Meanwhile, some netizens wondered if D.O. and Kim Woo Bin were together for schedules related to the tvN series 'Green Bean, Red Bean', which recently began production for a new season.
