is this worth it?

i was intrigued by this story cuz it reminded me of <Death Is The Only Ending For The Villainess> however novel reviews are making me not want to continue this. and yes while i did enjoy reading this so far, the whole ex gf is currently inside a child's body and has the potential to be the protagonist's love interest/part of his harem isn't really doing it for me. if ex gc and mc enter in a platonic relationship where they both understand and wholly accept what happened between them and be friends and joke about it and other shit, i might continue to read this. other problems w the story so far has been mentioned by novel reviews
