She's Adopted a High School Boy!

男子高校生を養いたいお姉さんの話

When his parents vanish and saddle him with crushing debt, high schooler Minoru Soramoto is rescued by his neighbor Shiori Kanemochi, who pays it off and moves him into her home. She dotes on him without limit, spending well beyond what makes sense, yet refuses to explain anything about herself. Grateful but wary, Minoru settles into a strange shared life with a woman whose reasons for taking him in stay hidden.
