Ilya Rosanov begins experiencing recurring, severe migraine attacks that leave him physically drained and destabilized. The pain is intense and throbbing, accompanied by strong sensitivity to light and sound, nausea, and occasional vomiting. From the beginning, he tries to maintain a composed exterior, refusing to acknowledge how serious it is. His pride, sense of duty, and deep fear of being seen as weak push him to continue training despite his condition. Internally, he is torn between physical collapse and the belief that stopping would mean letting his team down.
