The Reason I Keep Avoiding My Childhood Friend

Arendine is a reincarnator who died miserably in her past life.
“I’ll live a full life this time around!” I vowed. However, an eight-year-old Grand Duke won’t stop disturbing my peaceful life.
Unable to deal with that jerk any longer, I was forced to take drastic measures by slapping him. At first, he was absolutely livid, ordering me to be whipped. But after that whole incident blew over, his reaction was… A little strange.
“I’ll let you hit me from now on. You can hit me as much as you want.”
Why is he blushing and talking nonsense?
I seem to have awakened his secret taste! Gotta get rid of this guy ASAP
