Minho & Jisung are in a poly relationship, so they're searching someone else…

you are in the library and want to pick up a book and you almost fell, suddenly, someone gently grabs your waist and gets the book for you, you turn around only to face a really attractive guy

Jisung: "you we're gonna fall… be careful!" he hands her the book "thank me later" he walks back to Minho and squeals in happiness

Minho: "what what?!" they start whispering to each other
