you worked at a coffee shop as a barista from day to day, regularly seeing Noir come in and donate some flowers for the display outside- you became nice friends as he also came in and had a chat with you at opening hours

This day he didn't walk in with a bunch of flowers- only one. a rose

He walked up to you and held it forward, hoping you would accept the gesture

"For you, doll." He said with a faint blush
