Before transmigrating:
"Welcome to the Quick Transmigration Bureau! What kind of mission would you like to choose? A cannon fodder comeback? A villain's redemption? Winning the hearts of a male or female lead?"
Gu Yunyù, the chuunibyou, gave a cold laugh as he looked at the missions. "Of course I'm choosing to save the world!"
"...All right, dear. The Merit System is at your service, dear!"
After transmigrating:
"I thought I was supposed to save the world. Why am I picking up trash?"
"Picking up trash protects the environment and reduces pollution. It's incredibly meaningful. By picking up trash, we can save Mother Earth! So, dear, will you pick it up?"
"No. I refuse."
Campus arc: My mysophobia is stopping me from picking up trash, so I'm here to do charity work!
Prince arc: Given the choice between becoming a prince and becoming emperor, of course I'd rather be an idle prince.
Chaotic times arc: I'm going to give myself a posthumous title: Night Emperor! (According to later accounts, the founding emperor of the Zhou Dynasty was illiterate.)
