Do you want to know?
yes :D
Not a big spoiler...
It’s the closet where he keeps the bdsm toys/tools (like whips, ropes, etc). That’s why in early chapters when the uke was making a round to see if the house was safe, the seme told him not to check the closet.
And if my memory doesn’t fail me (which it can, since I e read so many bdsm mangas xD) he’s getting a riding crop - it’s a type of whip/spanking tool.
Oh shit I was just abt to say u was mean Bc I didn’t see the part where u spoiled it
Oh no what does he have in there?
