Si An and his family celebrated his birthday together while on vacation on Jeju Island!

The beloved “The Return of Superman” star and son of soccer player Lee Dong Gook turned four years old (in Western reckoning) on November 14.

His mother Lee Soo Jin shared some photos on Instagram from the family’s celebration, as well as a video of Si An thanking everyone for the birthday wishes and sharing his love.

She wrote in the caption, “Daebak Si An. Fourth birthday. Our trip to Jeju Island. Chicken party. Pajama party. All five brothers and sisters are healthy, so thank you. Thank you for our happy times together. It’s sad that time seems to be going by so fast..; Thank you to everyone who has sent birthday wishes.”
