Dear [男生名字],
I hope this letter finds you well. I wanted to take a moment to express my feelings for you, as I find myself thinking about you more and more each day.
From the moment I met you, there was something special about you that drew me in. Your kindness, intelligence, and sense of humor are just a few of the things that make me admire and respect you so much.
As we have gotten to know each other better, my feelings for you have only grown stronger. You have become someone who I trust and confide in, and who brings joy to my life every time we talk or spend time together.
I know that expressing my feelings like this can be scary, but I couldn't keep them inside any longer. I hope that you feel the same way about me and that we can explore where our connection might lead us.
Thank you for being such an important part of my life, [男生名字]. I look forward to hearing from you soon.
With love,
