He's my top visual like seriously when you see their photoshoots he seriously stands out

To be honest, I like how his slightly crooked teeth give him more character to his smile.

Ong Seongwoo getting-nervous-face is masterpiece OMG......

A handsome guy is not afraid of showing his funny side coz he knows he's handsome! Period.

Among Wanna One, if not for the voting, he is actually the most Center Material, first of all, He sings most of the hook of the Wanna one song, He can devour any dance breaks, he is a visual, he is also a gag man. He is perfect for a center

He's my first pick from the start!

He's really cute aigoo 😍ㅋㅋ

I see a glimpse of Dylan O'Brien in him. Both are my favorites. Ong is all-rounded 😍

Im proud i chose him as my no.1 the first time i saw him

OSW should have been in Top 3; in fact he should have been no. 1. He’s the most talented and the most versatile,.

Ong Personality and talent ,charisma and looks !!!

Let him use more chokers, its a blessing to my eyes 😍

Loved him from the very first episode, got snatched by Daniel from the third episode. Turns out they're husband and wife 😂😂

Ong Seongwoo how are you so perfect😔

seeing actor Ong now, it is indeed a face of the group

He stole my heart from his very first audition, and I know that I stan the right guy. He is the reason why I watch PD101 bc I want to watch his gags and his talents as well

Ong SeongWoo <3 <3
