Q1: Did Seong-je save Jun-tae because they had a secret past connection?
A1: No narrative evidence in the webtoon or drama confirms any prior personal relationship between Seong-je and Jun-tae. The intervention was entirely contextual, driven by the immediate dynamics of the Eunjang High conflict and Seong-je's disdain for Choi Hyo-man's undisciplined behavior.
Q2: Does this rescue officially make Seong-je a member of the Eunjang crew?
A2: Seong-je remains an independent operator. While the act generated mutual wariness and a temporary cease-fire with Yeon Si-eun, Seong-je never swore allegiance to Eunjang High or integrated into their core circle.
Q3: How did Donald Na react to Seong-je’s intervention?
A3: Donald Na viewed the insubordination as a calculated risk factor. Rather than ordering an immediate purge, Donald monitored Seong-je closely, recognizing his value as an elite combatant while preparing contingencies should his defiance spread.
