Seojoon and Hyungseok - Who Tops? (Patreon)

I might do a little NSFW doodle of side ships :D

Hyungseok has a reaalllyyy nice body (especially for a sub-Beta), he's surprisingly athletic with broad shoulders and nice abs. Seojoon is taller, but also lankier; despite being an Alpha, he's not too fond of physical exercises. The heavier thing he had lifted is probably hardcover encyclopedias. 

I personally find Seojoon to be a cute, awkward nerdy bottom and Hyungseok the older, equally nerdy top who loves to switch, but I know your BTS preferences, so.... let's just vote :"<
