Ok, the song is on this link.

Block B's P.O will make some girl very happy, hopefully I can find a guy as sweet as he is~

To the future Mrs. Pyo,

Please take good care of this boy, he is perfect in every sense of the word. He deserves loyalty and true love.

Thank You, BBC

To P.O.

Saranghaeyo~ You are perfect don't let anyone tell you otherwise!

Love, BBC
