On February 9, the actor posted two black and white images via Instagram. The first photo illustrated a 'schoolboy' look, as Yoo Ah In made a dandy pose wearing a sweater and plaid shorts.
While the second one featured Yoo Ah In baring his chest, exposing his briefs with a hand in his pocket.
Seeing this, netizens commented, "A marvelous actor for sure," "Both concepts are fantastic."
