Manga 4-book set

This is volume 3 of Hetalia.
The cross-dressing illustrations might be similar.
Hetalia seems like it would have characters you'd become attached to.
It feels like I was into Hetalia for a while there.

This is volume 1 of Holiday Bad Guys.
Bad Guys who like pandas.
They're cute.
I accidentally bought it even though I already had it.
There are several volumes out, and they're quite interesting.

This is volume 1 of Cross-dressing Cosplayer and Younger Brother.
I didn't find it that interesting, so I'm putting it up for sale.
The other three books are recommended, though.
But the illustrations are beautiful.

This is volume 3 of Motohashi Brothers.
The illustrations are intense, but
it's quite interesting.
I accidentally bought a duplicate of one I already had.
However, it has a bit of BL in it, so
if you're not comfortable with even light BL, it's probably best not to purchase it.
