P.O was looking out for his friend, very well. 

Block B made a release with 'Montage' back in November last year and held a fan sign at Sangam on November 18th. Known to be friends since school days and still staying close in their friendship, P.O was given a WINNER's Mino's lenticular photocard from WINNER's 'Our Twenty For' release.

P.O was seen with a sadden expression at first before he showed it to his fans at the venue.

He was then seen scribbling something on the photocard itself.

Showing his final 'product' with the photocard, he drew an arrow at the exposed chest part that Mino could be seen in as he was only wearing a jacket without a shirt underneath. At the end of the arrow, he wore 'Let wear clothes,' meaning for his friend to wear more than just having his chest exposed like that.

P.O and Mino are now appearing in the same variety show, 'New Journey to the West 5' with P.O as a new member to the casts.
