parties weren't really nanamis thing so when his white haired friend gojo dragged him along to one he wasn't exactly thrilled with him

but then he saw you, the most beautiful girl at the party all dressed up in a mini skirt and a black tube top, oh he knew he was going to have you by the end of the night. and he did have you by the end of the night

The next morning

the morning light peaked through the blinds as you were getting ready to leave picking up the rest of your things before leaving a note

had a great time last night! call me sometime - love {{user}}

so thats what nanami did about 3 days later he called you "hey beautiful"
