I don't know but I think his revengers comrades deliberately dump wishes to him so he won't think of killing himself once he got out of the dungeon since he has to carry and fullfil their wishes for a long time.
There’s some he can basically never finish because they have no end (like eating 3 meals a day etc) but for the rest he actually don’t have many (don-t remember the exact number but I think it was something like 16? A small number) and a lot of them are already started or almost done (the one he talks the most about are the cookies, the fishing one, the cloud one, the queue one and the sport one. There’s a few he finish during the story too like the knitting one)
*Spoilers about the wishes*
They were made to never end, his companions asked for things like he should only sleep in beds, have 3 meals at day, exercise everyday, etc so he wouldn't drow in depression and became suicide
Realistic the wills will never end
I know MC was given a lot of wishes. But I’m kinda curious how much more he has left. I know he already finished a lot and half way/close to done on some.
