I don’t think it had much importance from what the author said he just set his foot on it then took it off I think it was to show Nanjo making himself comfortable while he looked around Moks room similar to if you visited someone’s home and lifted a picture frame to look at it just a mindless action

Guys...looking back at chapter 39 the author especially added a whole drawing of Nanjo taking and standing on Mok's skateboard...I was kinda confused about why our author added this scene... Nanjo wanted to be taller than Mok to kiss him...while Mok was showering Nanjo already waited to kiss him...-.-....crazy
