In the live showing of MBC radio program 'Sunny's FM Date' on February 10, Sunny relayed her happy birthday wishes to fellow member Sooyoung.

Someone requested the Can's song "My Spring Day," so Sunny said, "Since I'm introducing 'My Spring Day,' Sooyoung, who appeared in [drama] 'My Spring Day,' comes to mind.  Today is Sooyoung's birthday, too.  I'll dedicate some time [to her]."

She then said, "Sooyoung, happy birthday.  Thank you for being by my side.  Although there's a big difference in our height so that our eyes aren't on the same level, our hearts are on the same level.  I love you.  Happy birthday.  Your Romeo."

She also introduced Naul's "You From the Same Time," saying, "A lot of people requested this song.  The Brown Eyed Soul members plan to release solo singles starting with Naul. Our Yoo Seung Ho oppa, who recently got discharged from the military, appeared in the MV."  

As he is younger than her so wouldn't have the 'oppa title,' she explained, "Anyone who's good looking is oppa," making everyone laugh.
