@Supercapp I don't think school has much to do with this series anymore. He would destroy Ha-min and So-Wol. He'll probably get put into fight class 3 by doing just that
@Lucifer I assumed the reason for his self harm was not feeling any closer to his goals, despite all of the pain he's had to endure. Feeling worthless etc.
@Lucifer Considering what he went through, he was a ticking time bomb mentally. Brutal training, repeated trauma and his obsession with his missing sister makes it pretty reasonable imo
