Recently, the actor made a public appearance with a brand new look which, unfortunately, seems to be disfavored by many. The unexpected hairstyle change has some fans in a "menboong" or mental breakdown, as they commented, "Heol.. why does he have a bowl of ramen noodles on his head..", "Seo Joon ah.. That's a no no", "OMG What happened???", "Oppa please come back..", etc. 

Despite fans'  shock toward the actor's new look, Park Seo Joon casually shared a video on Instagram of him nonchalantly munching on a burger, showing off his blonde hair as if he's completely unfazed about the hate. 

What are your thoughts on Park Seo Joon's new hairstyle?
