It's a manga about a goddess who want to become a high school student after her temple being abandoned, so she try to take the MC to the god realm and ask for permission to leave, she lied about liking him but every lie she said, her forehead will say the truth, it's comedy and slice of life. I remember there was a chapter where they would stop for a bento and she got turn into a oni while MC turn into a dragon

This was absolute hell to track down because no one has ever added any tags for it. I'll get to that shortly.

MU shows no updates, but Ch 34 just got released on mangadex, it's just that they have no group so the releases don't get listed.

Thank you so much, the artsyle stucked in head so much that I been thinking about it for days
