honestly... I just love this song~ their voices are so soft and no doubt that they both are really talented~ ^^
For those who love ballad & slow type of song...
you guys should check this song out =)
This is the live version of this song ^^
Dongwoon and Doojoon have really shone in their performance of their self-composed track,
“When the Door Closes“, with their solid vocals plus the piano playing skills.
