   Summary

   When a legendary Black Card is found in Dorm 5, Chris and Miyuki uncover a shocker in Eijun’s sealed records: the loud, reckless freshman is secretly a top-tier genius and the heir to a global billionaire empire. Confronted in front of the entire team, Eijun’s energetic persona completely shatters into tears—revealing the heartbreaking truth of why he hid who he really was. But as Seidou opens their arms to accept him, a single question remains... now that the truth is out, can Eijun truly escape the shadow of his past?
