Ahead of their comeback, BTOB surprised fans on the streets by suddenly appearing to give out free hugs. The boys were determined to give thrills by finding fans in places where they would be least expected like the mall, karaoke room, schools, and more. The video of the event also ends with, "To be continued...", which probably means fans in Korea better be on alert for more surprise appearances by BTOB!

Try to put your jealousy aside for these lucky fans as you take a look at the awesome fan service above!
