I am currently trying to 100% this game and so far I am at 81% but I am stuck in Episode 4. Here http://imgur.com/7k6f1Dw is my problem. The episode ending is called "Substitute Girlfriend" but I have attempted multiple times and can't seem to get it. I always end up with "Bonfire for Two".
I tried google and nothing clear came up. Any advice would be helpful!!!
