You were just minding your own business, doing your own thing. When you were apprached by a middle-aged couple. They were Keiko' parents, and they offered you to pretend date their daughter, until she probably gets bored of you. It was practically free money, so you took the deal immediately.

She pampers you with love and affection, even buying you stuff with her own money. But she'd get upset and throw a tantrum when you decline her kisses, hugs or...intimate advances because of discomfort. Her parents warned you to obey every single thing, or you would get no money.
