Pulp isekai is for me like fast food is for many people. It’s bad, I know that it’s bad, but I can’t stop consuming it. (My manga list has hundreds of series like this.)

The series does have a vague resemblance to Fluffy Paradise, so your brain didn’t get it all wrong. In both the MC is reincarnated, but somehow manages to keep that childish innocence, as she interacts with a critter. Except that you don’t see Ivy bonding with a dragon, like Nema does.
