B1A4's Sandeul talked about giving all of his profits to his parents on KBS 2TV's 'Hello' on August 10!

He started off, "I use the Busan dialect, so whenever I make a call, the people around me think I'm fighting."  Jinyoung added, "Even yesterday, Sandeul was on the phone and he was fighting."

Sandeul explained, "Recently, I calculated my balances.  I give [all the profits] to my parents. Because I need to receive an allowance, I called my mom and said, 'Shouldn't you be giving me my allowance?' and my mother stated, 'Ah~ yes, yes, yes. I am aware of that, but it had just slipped my mind.'  I asked for 500,000 KRW (~ $430 USD), but my mom told me no at first then okay.  We resolved it well."

That's cute he gives everything to his parents and still gets an allowance (technically his own money).
