Today is NCT Mark's 26th birthday🥳

Mark celebrated his birthday

I want to return the love I received from Season 3. r_e__m___ We've launched a treasure hunt event to find Mark's favorite items posted on his Instagram account.

I think this will be Mark's birthday that he will remember for the rest of his life.

If a sweet guy like this were my favorite, I would be so happy!! I'm so jealous of the season mates🍏💚

Happy birthday Mark🍰💕
