Lee know and Han are the popular kids in school. Everyone thinks they should be friends... but they apparently "hate each other" One day some girl points out that they have matching tattoos. Lee know has a moon and Han has a sun, they have it on there dominate arms. they try and tell them that it might just be a coincidence, and their classmates believe them, who wouldn't? They "hate" each other, right? What their classmates don't know is they have a secret... Same with Changbin and Bangchan, Felix and Hyunjin, anddddd Seungmin and Jeongin.
