San is ATEEZ's performance weapon — known for an on-stage intensity that is almost unsettling in its focus. His expressions during performance are described as being in a different world entirely. Off-stage, he is warm, talkative, and known for his abs (a frequent fan discussion topic). His childhood friendship with Yeosang is a beloved fan storyline.
