Jungkook was born with a rare condition that made his eyes change colour according to his emotions. He refused to leave the house without wearing contact lenses; afriad of what the world would say if they saw his true self; terrified that they would shun him out for being weird or different. But all that changed when he met a certain Park Jimin.

Jimin still visits Yoongi. 

Jimin starts keeping a diary the day he met Yoongi.
