Synopsis

Beomgyu hates the question: 'What's your favourite colour?' because he can't give an answer.

Born with Achromatopsia, Beomgyu is unable to see any colour, so Yeonjun decides to teach him how to recognise them instead.

"Pink. That's the colour of your cheeks right now." His voice is as soft as a lull when he tells Beomgyu, feeling shy.

Unbeknownst to Beomgyu, Yeonjun's are the exact same.
