Can i ask you how to get to sex ? cause i couldn't i lost in AGUST but i couldn't get any CG sex , when it start ?
You need to get them up to lover first - visit them during the weekdays whenever you can (for Shuu, every Monday or Wednesday at first) to get all the friendship event scenes, and keep calling them or taking them on dates on Sunday. Once you do all the event scenes and the heart is full (talk to Fundashi at the park to check), keep visiting them and you'll get a confession scene and become lovers.
Once you're lovers, take them out on dates and then afterwards to the love hotel and you should start seeing some sex scenes. Some CGs happen automatically, but for some you'll need to buy specific costumes or toys. Hope that helps!
I take it you couldn't pay the rent in August? That's a bummer. If you're having trouble with the auditions, I found I could get by just by taking part-time jobs if I needed to.
