I'm trying to find a rpgmaker game (at least i think it was rpgmaker) where you play as some fat otaku guy and suddenly a loli knocks on your door and starts living with you. You had to work some jobs to earn money and train her? Something like that. It wasn't translated so this is what i could make of it. Also i think if you ignored her or didnt do what she wanted she would go to your neighbor's house and fuck him lol. Anyway that's all i remember.
