A letter Akko may or may not have written to Mari.
Set before the school trip.

[insert usual disclaimer about not owning the manga or the characters here]

Dear Mari,

I'm writing this letter to tell you how I feel about you. Maybe I'll never have the courage to tell you in person, but maybe i can send these words to you.

When I first talked to you, I simply thought you were cute. To be honest, I was envious of your big eyes and your silky smooth hair. I wanted to be your friend, wanted to help you become even cuter, even more beautiful, like polishing a raw diamond.
After you got your new hairstyle, everyone warned me that I was trying to force my favourite things on you. Yet you accepted all that, everything about me. I was so happy to have you as my best friend.

I first noticed that my feelings changed after the day I gave you makeup advice. At first, I didn't know what to make of these feelings. I just felt lonely and sad when we were not together. It took me a while to realize the meaning behind this, to realize how I really feel about you. Just being friends with you is no longer enough for me.

Mari, thank you for being my friend.
Thank you for falling in love with me.
Thank you for making me realize my true feelings.

I love you. I love you more than anything else.

In love,
Akko
