The Master-Servant Contract That the Eldest Lady and I Reverse Day and Night

"Miss, from now on we will have our own affairs. I will call you Miss during the day, and you will call me Master at night." "As long as you save me, I can call you dad, or husband?" "You think so, are you so poor that you can afford to support me?" She is a down-and-out daughter, an idiot who only cares about revenge and only has money in her eyes; the eldest lady only practices swordsmanship to become a sword master and earn the minimum living allowance to earn money from the country. I am a visitor from another world, a disciple of a sage who is cursed by knowledge and suffers from collecting addiction. I travel not to hunt for treasures but only to waste money. Anyway, I am not the one making money.
