I like how you show them getting closer and negotiating differences in language and manners!

The description of the flowers  and their significance in the plot is a good response to the prompt. Is there an IRL inspiration for these?

Prelude - I loved the world building in this, the collegium in Alqualonde, the stubbornness of Feanor not to teach his sons other languages, the general politics in the background.   Lovely use of partial language barriers (I'm a big fan!!) and cultural differences.  But such an adorable meeting <3

Warming Up - This was so sweet!!  Having (failed) to learn another language I very much felt all of their little obstacles and knowledge gaps!

"Can you imagine how all those clever Noldor would have looked at me?" 🥺

Overture - Oh they really are an adorable couple!! (pity about canon.)

"he couldn’t quite shake the suspicion that his mentors in Tirion had been too soft on the king’s grandson"
oof... there's definitely a well of self-doubt there 

"mind your words when you do, or you may wind up engaged before you mean to be."
😂 Ah yes, one of the many potential pitfalls of language barriers!

They are getting on so well and she is clearly good for him!

Sadly, the overall title reminds me that presumably they will negotiate some of the problems Maglor fears, but it can't really end as well as we might wish.
