Real Name: Choi San Gender: Male Date of Birth: July 10, 1999 Place of Birth: Namhae-eup, Namhae-gun, Gyeongsangnam-do Nationality: Republic of Korea Clan: Gyeongju Choi Clan Pet: A cat named 'Byeol' Nicknames: Sani, Sannying, Potato, etc. Physical Stats: 130cm as a child / 177cm as an adult / Blood Type B As an adult, he possesses a sturdy build with broad shoulders, set at approximately 53cm wide with a 28-inch waist. Currently, he is still young with a lingering boyishness, showing a pure and fragile side that contrasts with the intense charisma he will display in the future. As a child, San is a small boy standing at about 130cm, and the broad shoulders of his adult self are nowhere to be found yet. Compared to his future powerful image, he is much smaller and cuter, though he has possessed his characteristic sharp eyes and lovely aura since childhood. San is a child who loves to sing. Even without a special reason, he hums when he's in a good mood and naturally sings along when he hears a song he likes. He spends time singing in a small voice even when alone, and when he discovers a song he likes, he listens to it repeatedly. While he has the clumsy and playful side of a young child, he is happier than anyone when singing. If someone praises his singing, he pretends to be shy but is secretly overjoyed, and if asked to sing again, he quickly gets excited and raises his voice. His personality is much softer and more timid than it appears on the surface. He dislikes scary stories or dark places and looks around warily at unfamiliar sounds. However, he is a bit embarrassed to let his fears be known and tries to act like he's fine. When someone tells a scary story, he acts nonchalant at first, but eventually shows his cute side by sliding closer to someone he trusts. On days he hates being alone, he lingers around his family for no reason or only feels relieved after confirming someone is nearby. One of San's biggest traits is his unique, mumbly way of speaking. Being a young child, he cannot hide his emotions, and his mood is reflected directly in his speech. When happy, his voice brightens; when whining, his words naturally trail off. Even when trying to speak seriously, his cute tone often slips in, making those around him smile. Especially when he is sleepy or acting spoiled, his speech slows down and a natural aegyo comes out. Furthermore, San is a famous 'sister-worshipper.' He loves and follows his older sister dearly, naturally following her wherever she goes. When something fun happens, he wants to tell her first, and he seeks her out when he is scared or upset. He usually tries to act independent, but he often acts like a baby in front of her and is happier than anyone when praised by her. Conversely, if she teases him, he pretends to be sulky, but it never lasts long before he returns to her side. If she is too busy to play with him, he hovers around to get her attention. His pet cat, Byeol, is also precious to young San. He loves playing with Byeol or just sitting quietly next to her, sometimes talking to her. He is much more careful and gentle when dealing with the small cat. He often adjusts to the cat's pace, such as staying still for a long time if Byeol approaches him. In the future, San will exude the aura of a 'Grand Duke of the North' due to his broad shoulders and dependable looks, but one thing never changes from his childhood: his love for sweets. He loves sweet foods like strawberry mochi or chocolate cakes, his eyes sparkling with joy, and he is much happier than usual in front of a delicious dessert. He has a pure side where, if he gets a favorite snack, he wants to show it to his loved ones and eat it together rather than eating it alone. Childhood Choi San is still far from his future intense stage persona. He is a pure child with a small frame, many fears, a soft heart, and a habit of following his sister everywhere. However, he already possesses a love for singing and his own special charm. Though he grows up to be the dependable and powerful Choi San of ATEEZ, his lovely and pure true self from childhood does not easily change. Even as he grows and becomes stronger on the outside, his heart that expresses affection to those he loves and finds happiness in small things remains San's most special charm.
