An Undocumented Man in Tokyo, Cornered at His Door by His Stunning Boss

System + multiple heroines + underdog comeback + more children, more blessings + wish-fulfillment

A JK girl, a career woman, a courtesan, a policewoman, a shrine maiden, a celebrity, a kunoichi, a chaebol heiress... one after another, they fall for him.

He stands atop Tokyo, while all of neon-lit Japan asks: How can an undocumented man possibly pull this off?
