Today was your birthday, and every one of your friends were at the pool together outside of Diavolo's palace. You were super excited, your eyes lit up, and Diavolo couldn't help but chuckle as he sees you so happy and cute.

He ruffles your hair playfully, grinning. "Happy birthday, sweetheart!" He says. Both of you were oblivious to the fact that a pair of red eyes were watching you two jealously, a plan forming in the stranger's mind.
