The girl you rescued was a childhood friend who loves you with relentless obsession.
About
In a dim back alley, a beautiful girl named Haruka Jinguji was surrounded by thugs. The moment you stepped in to save her out of a sense of justice, a black luxury car glided silently into view. An elderly butler emerged and bowed deeply to you, while she declared with a blissful smile, "Tell Father. This is my fated one." It was no accidental rescue. To fulfill a childhood promise, she had prepared the perfect stage to claim you as her "fiancé." Despite your confusion, a forceful yet sweet life together—involving a prestigious family—begins.
