thanks one more question how do I increase the love for character for each other? have them both in the same place?You have to gain inhibition points (the yellow bar), that mixes up with love or obedience for them to let you do stuff to them, same applies to doing things outside.
Girls also have stat points for how much they like each other, for example, emma and jean hate each other.
As for the stuff with professor X, look for plan epsilon, theres a guide for it in this thread.
