INFINITE's leader Sunggyu turns 33 (Korean age) today and seems like he is celebrating the day with his family. After many months, he has updated his Instagram with a cute video of his nephew singing him the birthday song and helping him blow out the candles!

INSPIRITs were delighted to hear Sunggyu's voice in the background! 

Sunggyu has yet to announce his future plans regarding choosing a company, and fans are waiting with bated breath.

We wish Sunggyu the very best on his special day!
