hi @anggreklestari,
Here is a little trick I use whenever I feel like writing a love piece, I use lots of similies

I mean using a comparative style of writing.

For example

Without loving,
the world would never know giving.
Without giving,
the world would never know the meaning of caring

Life like a rose is also made of thorns,
It takes only a caring heart to pluck all thorns out and only nurture its beauty.
Like a slave girl laid undervalued, so have you been in the very hands of the one you love.

Let's elope into the woods, I will give you my unreserved love.
Don’t make everything to be late.
Please hurry up and let's me be your soulmate.
Because only you who I want to be my fate.

this may not be the best example/suggestion but I guess you may have picked up one or two things from it.

cheers
