I feel you co owning is ass i once had an oc that was co owned because i got it and this person who i called 'friend' had wanted that pony too so for some reason i said yes to co own lol then one day i even barely spoke to them anymore so I was like sorry but i was the one who got it lol i don't want it to be co owned anymore and they got upset?? it's such a hassle, it leads to a lot of confusion one thing is like you have shipped characters and you co own children of said ship or something but even so it's more likely it's with someone you've known for a while

i've done it once or so and I do not recommend x_x
