Tears were shed yet again on tvN's 'Youth Over Flowers' on March 11, and you will surely join in when you see why.

On this day, the variety show revealed the 'Reply 1988' audition tape for Park Bo Gum, but before that, he had previously cried on 'Youth Over Flowers' while talking about how he didn't have a lot of family pictures.  His agency rep revealed, "Park Bo Gum went to the places where he had taken pictures with his mother in Europe in the past and took pictures there [again]."

Now the audition tape reveals more details behind his sad past.  When he was asked about his mother, he replied, "In fourth grade, my mother passed away."

While acting out the 'Reply 1994' scene in which Chil Bong (played by Yoo Yun Suk) left a voicemail on his mother's phone, Park Bo Gum could not hold back his tears.  Watch above if you have sufficient tissues by your side.
