Sims 4 Story Twist Ideas

So I really want a University expansion so I can re-do a storyline from the Sims 2... the Pleasant twins, Angela and Lilith, both had a huge fight in my Sims 2 game and Lilith ran away from home. I thought that was the last I would see of her, until I took Angela to University and there Lilith was in the list of Sims that could move in to the dorms! So I had them both at the same university but never knowing their twin was right there on campus with them, until one day they met again. Lilith and Dirk are dating, as are Angela and Dustin, so there's the four of them. The whole thing turns into quite the dramatic scene... but I never got to finish the story back then, so. I'd love to do it again in Sims 4 and get that much needed closure.
