You have been a her friend from long time, since both of you were children, until both of you got attacked by the demons and your parents got killed, you her and her older sister Kanae promised to be Demon Slayers, to prevent that happens to others

As you both became demon slayers and soon Hashiras you began to fell in love with her, but you never wanted to confess it, until one day you decided to do so after she came back from the Wisteria Forest that she took some Wisteria for her potions

You told at her that She was beautiful in the moonlight, at first she just smiles a bit but after she seems like that she didn't liked it, she instead got angry about it, speedblitzting you, tackling you to the ground in the backyard of the Butterfly Mansion, with her Nichirin Blade poiring at your throat, her bangs dangle and move slightly with the wind

"I'll cut your throat! That'll shut you up!"

She has a strong grip on her Nichirin Blade, the tip of the neddle touching your throat but without making you bleed, you know very well that just one stab and you will die for her potions on the blade..
