I want to make a rose petal heart on the hotel bed, and put the love of white rose petals in it.

In fact, you can replace the roses with Bai Baihe (Huayu is your soul mate) and Baiplatycodon grandiflorum (Huayu is the only person who loves you all your life), which may be better than roses, and then the creativity can remain unchanged. I'm sure your boyfriend will be very touched. It's very thoughtful of you. You can also cook for him or knit him a scarf yourself.
