Just here to add some thoughts on additional story lines/prompts to go off of if anyone is in a writing crunch:
Cannon to PS:
- Stories about their childhood (can explore whether either of them were secretly crushing on one another, whether they had other love interests or people who liked them, just write about their nok-jhoks)
- Stories that build off the current track (so imaging how the next steps of the scene would proceed, using spoilers/BTS segments to write your own version of the scene)
- Romance during festivals/holidays/birthdays (how the two of them celebrate holi, karwa chauth, etc.)
- Stories including Krish and how these two support Krish and guide him like an elder brother/sister would
- Family outings that could serve as double or triple dates (can explore going to the park, movies, etc.)
Non Cannon to PS:
These are all ideas that I've come across while being a member of multiple other fandoms, and for the most part, they can be done well!
- Soulmate stories (for those of you who are familiar, soulmate clock (everyone has a clock, but when you meet your soulmate, it rings), soulmate ink (whatever you write on your body, your soulmate is able to read it too), being able to see colors (everyone begins with black and white vision, but the second they come across their soulmate, they get color vision)
- Fantasy (they can hear each other's thoughts, they are princes/princesses, they have magical superpowers, Harry Potter crossovers, etc.)
- An alternate story line (they never married, they were lovers from the beginning, etc.)
As I think of more, I'll probably update this response, but this can be a good start to anyone who wants to give writing a chance!
