I should start by checking if there's a known art installation titled something similar. Maybe it's a conceptual art piece where two children interact with a sandbox, highlighting themes like play, cooperation, or conflict. Sometimes artists use children and sandboxes as metaphors for creativity or the human condition.
Honestly just some trash writing and sub par art. The NTR aspect is trash too, it wasn't written well at all and is just gratuitous garbage. I'm not really into NTR but when it's done properly then it's atleast readable. The MC is lame and the "villain" is worse lol actually all the characters are poorly written and just not interesting in the least. There's only a minimal amount of chapters but I still wouldn't recommend wasting your time on this.
