It's INFINITE's youngest member Sungjong.
On a special day like this, I wanted to give you a quick update on my life. I have been having a fulfilling day today with many kind words from people.
Woollim's CEO, who was the first to wish me a happy birthday, my loving members, our Woollim family, many acquaintances, and precious family members, thank you.
Finally, INSPIRIT, who I miss so much, I'm always longing for you, thinking of you, and missing you. I hope you're always happy.
INSPIRIT, I love you."
