Naruto System in One Piece - Chapter 528: Antidote

System: You are the only human who meets the binding requirements of this system, please bind with me!

Su Yu: I have money, good looks, power and influence, why should I bind myself to you?

System: You haven’t fallen in love ye-

Su Yu: Aiya! My stomach is hurting all of a sudden!

Su Yu bound himself to a system; his only task is to scatter some IQ to the brainless male protagonists. The soft-headed male protagonist chases after the female protagonist, the male protagonist with some intellect chases after him. He feels that something is not quite right…

Su Yu: System, is there something common between these male protagonists?

System: Yes, they are all male protagonists.

Su Yu: …Suddenly I don’t feel like talking anymore.

Male Protagonist who has been scattered with some IQ: Then don’t talk, just kiss me.

Su Yu: …Suddenly I don’t feel like doing the task anymore.
