He was eventually cast by KOZ Entertainment, the label founded by Zico, and trained there for about two to three years alongside future groupmates. His selection as a BoyNextDoor member came through an internal audition process, and the group was announced in early 2023, marking the start of his professional career.

Taesan commands a growing global footprint as the tallest and most versatile all-rounder of BoyNextDoor, drawing attention from K-pop enthusiasts worldwide who track his evolution from rookie to seasoned performer. Despite this rising profile, iFANN's Global Fame Engine has evaluated Taesan but currently finds he does not hold a placement in the published rankings for the Global Top 1,000 or any Top-100 scope list. This unranked status reflects a dynamic period where his fame is concentrated within dedicated fan circles rather than broad general audiences. The community rallying behind him is officially known as ONEDOOR, a name that signifies their role as the 'one' neighbor next door to the group. This fandom demonstrates remarkable digital organization, with members actively driving streaming metrics and engaging in direct, heartfelt interactions with Taesan during special milestones like his August 10th birthday celebrations. Fans frequently highlight his transparency regarding family life and his production contributions, creating a culture built on shared relatable stories rather than distant idol worship.[edit]

His stage name translates to "big mountain" in Korean, chosen specifically to symbolize stability and strength.
