Dear Imogen,
They say February is the month of love, so I find it proper to write you letters as to why I love you. Although you may not ever notice my existence, I notice everything I could about you.
"A real love is not having you beloved in bed but in your dreams and thoughts." -M.F. Moonzajer.
My dearest love,
Your secret admirer.
P.S.: Your smile is the prettiest I've seen in my entire life.
