Yeah
pretty sure he figured it out because of the macaroons
madeleines* not macaroons
Oooh i thought he only found out from chapter 36 ..... On what chapter is the madeleines thingyy??
He already suspected it from neutaaa's new skin (that looks just like him irl) which is why he created the side account. Then he sent neutaaa a message and heard his neighbor receive a notification. And finally he received a picture from neutaaa of the cookies he gave his neighbor. Madeleine happened at ch 30 but back them jigu was still trying to rationalize it as coincidence.
did black hair find out?
