Im genuinely stumped for what I should write for this next chapter

I’m writing this fiction, wlw to be exact where a Artemis nymph and Apollo nymph fall in love, and in the end the Artemis nymph turns into a tree. They just finished their first date, what should come next? I would love it if you could be detailed, detailed as you can be. The Artemis nymph becomes a tree because they aren’t supposed to fall in love, to be clear.

here is the full plot:

Liana, this Apollo nymph falls in love with Katrine a Artemis nymph. Them being together is forbidden due to Lady Artemis’ rule: he nymphs can’t date, have romantic/sexual interactions with others, nor fall in love. it is an oath to being her nymph. Liana writes a letter to Katrine confessing her feelings for her, and they’ve already had their first ‘date’

im not going to link the story its because i dont want to self promote if thats not allowed, but if you ask for it, i will give your the link
