Mori thinks that Sanguine is a cool guy but he's really only gotten a strong impression of him in max misery mode. He would like to get to know him outside of max misery. Obviously it's understandable, because BE=DE messed up in a big way and are all consumed by guilt, but Mori thinks that just because they made a mistake that they are making attempts to atone for doesn't mean they should hate themselves and feel so down, which is why he tried so hard to comfort Sanguine. He's been nothing but sweet. Sanguine really seems like he needs a friend, which Mori wants to be.

Sanguine is a nice guy that needs to be less hard on himself and have someone cheer him up is Mori's basic impression.

Reverse?
