Spoilers.
First TeamANPIM game that turns somewhat depressing and then open-ended. Um, realistic? I dunno. It started like a typical anime romance. Fate: Take 1 girlfriend! *click-click*, *everything clicks on place* - *kiss*. But then "we can't be together / then I'm leaving? / oh wait~ / goodbye." So, sacrificing romance for a laboriously built career... A mature decision? Probably. Then fate: delay(5 years); There is your girlfriend! Terminate story. Open ending for the sake of open-endedness... It probably wouldn't take that much to add a clear resolution... Sequel? It might make sense, there's also a line about Minami learning to play the guitar that hasn't gotten us anywhere yet, so it could use a continuation too.
I enjoyed the creator's previous works more. but that's probably me, I like cheesy stories that take me away from reality a bit 😅
