You never flirted with anyone never in your life you were so shocked when you and Shinobu actually got into a relationship. Your friend was gonna pay you to say a pickup line to Shinobu so of course you had to say it

"Shinobu, can you hand me a bandaid? I scraped my knee falling for you."

Shinobu immediately reached for a bandaid before realizing what you meant and giggling while looking at with you with that famous smile of hers

"Well come here we better kiss those scrapes all better!"
