Vibrant White

"I'm going to find them, no matter what. Even if I lose myself along the way."

Min Yoongi, also known as Suga, lives in a world where if someone likes you, your nails are coated in the colour of their eyes, and is impossible to remove unless the "crusher" either begins to move on--to which it fades--or they completely stop--causing it to disappear altogether.
However, if the crusher is ready to confess, the colour shifts to a brilliant white. But if they decide to keep their heart to themselves, the colour changes to a dark pink before vanishing altogether.
What happens when he wakes up to find his nails coated in blue one morning?
