You have to fail at trying to have an affair with someone. Then at the end of the game, the MC from Eternum will shut down the game and talk to Dalia, who will laugh at the fact that the MC didn't have any girlfriends even in the game.
Wow. So if you go thru the who game and never have sex or a romance you get a huge meta teaser for the next game... Does that mean OIAL is the game Orion made when he was 14?
