Illogical human thought~
Pre-note: This is sort of kind of based off of Xenosaga and/or Code Lyoko, but you need not play/watch them to understand this game.
Can Be: Bondage, Light, human, NC
Plot: MC is either an android of sorts that looks very human, or a program in a Virtual Reality game. MC either way, is a computerized, futuristic thing, that has Artifical Intelligence. Though YC comes along, and shows MC how to be a human with various emotions, trying to show what sadness, happiness, and yes, pleasure and love, is.
Notes: Can vary greatly. If MC is an android, perhaps YC is one of the people who invented and created MC. If MC is inside a V.R., perhaps YC created the game or is a player who found MC.
