How do you get Ten's route?
Finish Juuichi's route.
I did.
What do I do after I finish Juuichi's route?
You need to get his Bad Ending. Once you do, and the credits end, you will get a notification telling you that you have unlocked bonus content.
k, also is the sex scene in there, cause when I did it with Juuichi, it skip.
I apologize for the late reply, Juuichi's scene is skipped when youre in android I think. You need to play in PC to change the settings in Preferences settings.
how do you get his bad route?
you pretty much have to go down on him even when he says not to iirc.
