Following his funeral on December 21, Taeyeon posted lovely selca of her and Jonghyun on Instagram and captioned, 

"Good night our Jonghyun. You did well today♡ This photo we took after we finished our makeup because we wanted a pretty cut. The day we matched in pink and sang 'Lonely'♡"

잘자 우리 종현아. 수고했어 오늘도 우리 둘 다 예쁠 때 찍겠다며 메이컵 다 하고 찍은사진. 핑크로 다 맞춰입고 론리부르던 날
