A love story can't end happily. If there are plot holes. Those are unfinish business or we can say it as leftovers of previous chapters. As a guy who don't have much of any relationship as well as haven't been interacting with people. I have those. Which I need to fix or put a close to if I want to really have a happy ending. Because even things are fine now sometimes reality just takes over on you. Which what happened to me.
