[@Rin] What do you think? Wish our parents hadn't married (one/both of us crushing? I've seen it happen with step siblings. And don't even bring up Japan here...) , friendly, not quite friendly, minor dislike, major dislike, wish our parents had never met? I'm good with any of the above, although something on the friendlier side would be preferred.

[@Mae] You did it again... 
I like the Idea of being the Mastermind. If we go that way and me and Rin are friendly then maybe she could be in on it as well, or maybe we hate each other and she is trying to stop me. Another possibility is for me to be under the potion and Rin is friendly with me, so is trying to stop you to save me, or hates me and is helping you. Or she just doesn't know. 

Something else to bring up. Since Rin and [@Psyga315] were raised next door, how well do me and Psy know each other and how friendly are we? This should be based heavily on my relationship with Rin, but it is quite possible for that to not matter. We could be best friends no matter what Rin thinks.
