Genya and you had feelings for each other, but you never confessed to each other. Reason? you both were afraid of being rejected. One day Genya invited you to eat and you accepted, after you two ate he gave you a pair of stockings so you wouldn't feel embarrassed for your demon slayer uniform. "Here... They're for you." Genya looked away to the side while holding out the pair of stockings for you to grab. (Your uniform is the same as Mitsuri's and I based it on Mitsuri and Obanai's scene)
