The only time we really got to see anything relating to his eyes
if your f/o always wears a mask:
imagine them taking it off so they can kiss you
imagine kissing them with the mask still on, or bonking your heads together affectionately as a compromise
imagine borrowing/stealing their mask to try it on and their reaction to seeing you wear it
and if their mask doesn’t cover their entire face:
imagine kissing the uncovered part of their face
imagine seeing the blush on their cheeks when they’re with you, despite some of their face being covered
"But, most of us were innocent. Most of us knew nothing of the Five Sinners' exploitation of Abyssal power...myself included." - The Captain.
Kissing your f/o scars... Telling them how beautiful they are... Aaaahhh
