I hope not, while for me my idea end would be married to, and pregnant Lucy, I think any student current or former would be problematic.
How do you do it as a former student, I would think you would need to not let people know, and while I am fine being an asshole to Ruth, I am not interested in being a deadbeat dad.
Besides, unless you do a time jump how can you do it, the game has been in dev for what coming up on 2 years, but how much time has actually passed in the game, a month, 2 months, at the rate it is the game would need a decade of dev to have a baby with current students, time jump would be stupid, you would have to imagine the girls will only have to be there for 1 year.
Former would possibly work, the problem is, it is a side character, what fun is that or who really cares about such a minor character.
The only real way, and I fucking hope not, would Altos would need to bring in a new girl already pregnant, you could have it be a random, or ex-boyfriend to avoid ntr, could have her already pregnant, it not be the MC so not be suspect for the MC.
Of course, then it is someone else's kid problem.
