The Day I Became a God (Kamisama ni Natta Hi)

I just wanted a light hearted anime to watch before sleep. An adventure, a fantasy. It started that way, it was even comedic, so I completely ignored the "drama" tag, but then in the last 3 episodes it did an 180 into the sad heavy stuff. And even though it had a happy ending, I still feel too down to go to sleep rn.
