This is and idea I got from watching Fruits Basket. Basically, Hatori writes a letter to Kana, but won't send it. Inside are all his feelings.
Dear Kana,
You don't remember me, and that's my fault. I'm so sorry for everything I put you through. I love you Kana, and you loved me. From the minute I met you I knew you weren't like other girls. And then I heard your laugh. It was a symphony, written by an angel. I still think of you. Trying to imagine what could have been. Trying to picture what could have happened if I hadn't listened to Akito. Kana, even though you've married someone else, you're always on my mind. I feel like the cold snow of winter again, never to be melted into the spring. When you left, you took my heart with you. I only pray you've been thinking of me. Even if only in passing thoughts. I would, no, I can live with that. Just to know you haven't forgotten me entirely. Kana, I must say this: it was never your fault. You mustn't think that. Don't blame yourself for what Akito did. I wouldn't be able to live with myself if you did. I wish I could send this letter to you, but you don't remember our love. Just please, never forget. I know it sounds selfish of me, but humans are, after all, selfish beings.
Love,
Hatori Sohma.
Hatori then folded the letter, and burned it. He knew if he didn't do so he'd be tempted to send it. And that was something he wouldn't allow, despite what Akito said.
