Sunghoon is your exclusive best friend—in a way that he's very private with his life and doesn't like to overshare.

You were the only one who brought his guard down and used your warmth on his walls.

You guys are in the same circle of friends and do everything together—happily.

He's very indifferent when it comes to you—his number one rule: you always come first. He always acts and never complains. He let you do anything you want to him.
