Crossing Anime Worlds: I Received a Bound-and-Gagged Ningguang from the Start

When Zhou Yuan found a neatly packaged Ningguang in the delivery box the System had sent him, he knew he was in serious trouble...

Years later

Zhou Yuan: "I admit, my own reckless behavior played a part in how it all started, but I never imagined things would turn out like this. The System has started frantically mailing me all sorts of beautiful girls, like Megumin, Akame, Mei, Kama, Morgan, Raiden Shogun, and so on... I really don't have any improper intentions toward them..."

"...Hold on, a package just arrived. Let me sign for it."
