I'm enjoying reading this story a lot, but I wish things like skill names would stay consistent throughout the whole story. I kinda wish the name orders would go back to the way it used to be at the beginning, too.The contract the jellyfish offered doesn't seem optimal. And I think it's funny that all the new baby monsters that come into Yoojin's care go through being put in their places by their older siblings, so to speak.

I think those are editor's suggestions/corrections. [] and () seem like parts added and parts to be taken out, respectively.
