How about putting together a book of love poems for him? You could buy a nice notebook or journal and write some of your favorite poems in it, or even write your own love poem for him. You could also add some small notes on why you chose each poem and how it relates to your relationship with him. Additionally, you could include some of his favorite poets and their works or a book of poems by his favorite poet. It would be a romantic and thoughtful gift that shows him how much you appreciate his love for poetry.
Or you can get him a star map with the date of your first kiss.
