You have to solve an "accident" or possible murder.Oh thanks for that. I just wish & hope that it wont turn into another game where a love interest teased all the way to the end and given two or three "full" fledged scenes for the climax, then one long epilogue with her and the game gets completed tag.
While investigating you will get closer to Isabella up to a full relationship. At that time the story will be far from over, so there will be enough private time with her, or even Alex and Isa together.
