... to wear panties that may or may not have belonged to your idol/man-crush

These are real, by the way. You could once buy a pair at Gearbox Loot (I have 2 lol)

Also I just noticed I put them on him backwards in the image sdfhskdfhksdf

Maybe he just likes to wear em that way... or maybe he got super excited to put them on and didn't pay attention.
That seems like a very Rhys-thing to do. Ah well. I also forgot his neck hair, oops. Maybe this plays before TFTBL events and before he grew out his hair a bit or smth.

Rare human art. I'm not as confident drawing them vs animal faces.
