Changbin is known for being "I love dark" among the members and that most of the times he wears all black. While Felix is known to be the sunshine of the group, he made the sun jobless just by smiling.

In their relationship, Changbin is the moon and Felix is the sun. They are total opposites but opposites attract. That leads them to agree on having a tattoo on the back of their palm. Changbin has a little crescent moon tattoo on the back of his right palm, while Felix has little sun on the back of his left palm.

It was cute, others members were so envious of it. The tattoos were prominent especially when they held hands. And they love holding hands so much.

Felix layed his head on his boyfriend's shoulder, they were in their ride home after the long hours of practice at the studio. Changbin smiled as Felix yawned shamelessly on his shoulder. He intertwined their tattooed hands before kissing his boyfriend's head. He knew how exhausted his boyfriend is.

"I love you, my sunshine." Then a kiss on Felix's little tattoed palm.
