Rainbow Nisha Rokubou no Shichinin - 1x25 - Season 1, Episode 25- Followmy.tv

Turtle goes to collect the debt for the old man. Mario and Lily search for Turtle to tell him about the doctor. Turtle returns, with the deliquent loanee. Mario and Lily take him to the American doctor for his check-up. Mario realizes that Turtle and Lily both unknowingly considered each other as family. After dropping him off, Lily leaves to take care of some things. Lily asks the old man not to lend Turtle the money, knowing that he wanted it to grant her dream. Lily offers herself to him instead, trying to get him to rescind the deal with Turtle. A week later, Turtle continues to worry about Lily, who has yet to return. He instead offers to have her be his housekeeper, rather than having her further degrade herself.
