I Rely on Sugar to Survive

Reborn unexpectedly, in a new parallel world, only by eating sugar can one survive, and only by storing enough "sugar" can one return to his original world. Sugar is a very subtle feeling when people get along with each other, a sweet, warm, and very warm feeling all of a sudden. The new book is inseparable from this one, which is equivalent to the story before rebirth, so the update of this book is temporarily suspended.
