Looking

Can someone recommend a short good manga read that’s sweet and romantic. No drama or angst.

Also I’m looking for a light novel. I know it’s QT or world hopping and the it’s BL. I’ve tried searching everywhere.

It’s a horror/ supernatural kind of world hopping where the MC completes tasks in each horror world and when it’s completed he goes to the next one.

One of the world was a world where he and several other task takers had to look after kids that were vengeful ghosts at an orphanage or daycare. The kids died because of a fire and all of the staff members were bad and abandoned the kids.

Another world they were filming a horror film and they had to act certain characters and the ghost would kill them off one by one during filming. The ghost was actually an actress of the horror film and she was taken advantage of and died horribly while they were filming.

I also remember that the MC was also really good at acting in whoever’s body he was in. He couldn’t OOC at all (out of character) and I think can’t really remember but the ML is his system that pretends to take tasks with him. So the MC thinks the ML is just a task taker that meets with him out of nowhere but he doesn’t know that the ML is also his system that has a human form to protect him.

I didn’t finish it and I left at a part where he transported to a new world and the system was somehow cut off from him. I AM DESPERATE PLEASE!!!! I really need help in finding it I’ve been looking for it for a whole year.
