If someone you like wants to express your love, it is a good choice to consider writing a love letter, which can avoid the embarrassment of possible rejection (%>_<%) and also give the other party time to think about it.
I would like to share with you an origami tutorial for a love letter envelope. It is quite unique. I hope it can help you and help you successfully hold the beauty/prince back O(∩_∩)O!~
Finally, use a red pen to draw a red heart full of love on the lower right corner of the folded envelope, and you can send it out~~~
