Become a Sword God in the Second Dimension

I accidentally obtained the strongest Sword God system and the most deceitful gold system, and became the brother of the game boss Bai. Devastated by the reality, I then took on the job of tutoring five idiot sisters with their homework. In school, I had to be attacked by Miss Shinomiya's eyes. If that's the case, forget it, but I want to know, isn't this an everyday world with love?! Where did this red-eyed ghoul drooling over me come from... The tentative worlds are Kaguya-sama, Quintessence, Ghoul... Maybe other worlds will be added in the future, like Married Woman Na or something... This novel and its characters are purely fictitious.
