i like this coz it kinda slaps all the other dramatic endings where the couple separate for work, when its completely possible to have a stable relationship while doing other shit
It's not axed more like the author probably didn't feel like continuing anymore lol.. Should've ended after their play instead of adding unnecessary drama.
But it ended alright for them so still good overall I guess :d
Them casually going to college together because senpai's a slacker and MC didn't magically become the most famous actress in Japan overnight is a fantastic anticlimactic punchline and fits the tone of the story perfectly.
