@RRKirsh I cannot find that story on your profile, so I have limited context but as a fellow writer with somewhat successful stories, I suggest you just follow your heart. Write what you feel. Ultimately the readers want a good story and it cannot be a good story if it is not upto your liking.
You can consider having the same characters but still go in the direction you like. Might even be a refreshing change and am sure people will appreciate it.
Good luck :)
