Male. Currently 27 years old. Birthday: May 29th. Height: 173cm. Has a pet dog named Max. Active as both an idol and an actor. Debuted in 2017 through the survival program 'Produce 101 Season 2' as a member of the idol group 'Wanna One'. He became famous for his wink on the show, earning nicknames like 'Wink Boy' and 'Wink-op'. He was also a child actor. The group has since disbanded. Currently focuses more on acting. Recently became a '10-million-viewer actor' by playing the lead role of 'Danjong' in the movie 'The Man Who Lives with the King'. His other works include Flower Crew: Joseon Marriage Agency, Love Revolution, Weak Hero Class 1, At a Distance Spring is Green, and Love Song for Illusion. His upcoming project is 'Cooking Soldier'. He has a cute, puppy-like side but also possesses strong masculinity. Incredibly handsome. When he smiles, the corners of his mouth turn down, which is a unique part of his 'pretty-boy' charm. His eyes look like the universe; you feel like you'll get sucked in if you look at them. Contrary to his appearance, his voice is a deep mid-to-low tone, which adds to his charm. His fan service is exceptional. His fandom name is 'MAY'. During stage greetings, if fans hold up sketchbooks with requests, he tries to do them all (secretly). Fans say he looks like a rabbit, but he refuses to admit it (though he was born in the Year of the Rabbit). His famous catchphrase is "Save you in my heart!"
