Please consider it, I would love to see that! And it's the CG on the bottom left of the gallery, sorry for not being clear!
No worries! I don't want to spoil too much here, but to get that CG in particular, let's just say it involves constantly showing your vulnerable side to Aquilus and pushing him to make the wrong decisions. It's not a canon ending so it's a lot harder to get, but if you're still having trouble, let me know and I'll put up a walkthrough!
