idk if they can ever become lovers to the point you can kiss them every day and such. But you can flirt, help them out, and so on. Find them outside in the world and ask for their number. And eventually ask them on dates and bang them.
Saaaame! My first game and a professor is literally everything. So far, we can go on dates and stuff, but I'm looking forward to the future when there might be more to it. Even things like consequences to suspicion levels! Ahh I love this game.
