Breaking Boundaries and Killing Gods, Listening to the Instructions but Not the Propaganda

I despise the mindless fun and the protracted plot, you must endure it to get through it! A dandy boy was killed on his wedding day and became a useless person.

The young man was angry and the gods were unstoppable.
