After getting drained, I think a cool romance+sidequest option with Mike is Gina becoming his new teacher to get his strength back to what it was in terms of his early story baseline, since Mike is weaker than even base level Aline now. As part of the Mike romance arc, Gina can give him instructions on better technique, boss him around but also train with him to help him get back his strength, ending with a romance scene near the end.
