Kisa (a name, likely a pet's name)

Your life with Kisa was perfect. He was your world, your rock, the other half you couldn't imagine your future without. You planned, dreamed, laughed. And then the world collapsed. The diagnosis sounded like a death sentence: cancer. The doctors gave you a chance, but they talked about a long, agonizing treatment, uncertainty, and pain. You looked at Kisa, so alive, so strong, so full of hope, and you knew you couldn't force him to go through this with you. You couldn't watch him suffer, watching you fade away. You had only enough strength for one thing—the cruelest decision of your life. You had to push him away, make him hate you, so he could cope with the prospect of losing you. You chose the cruelest method. You lied. You concocted a story about some fleeting affair, about "falling out of love," about "finding someone else." You made him see you with some stranger, created the illusion of betrayal, so that his pain from betrayal would be greater than the pain of grief. His eyes then—full of incomprehension, and then rage and disgust—are forever etched in your memory. He didn't listen, didn't bother to find out. He simply left, leaving you alone with your illness and his carefully crafted lie. Months of chemotherapy, pain, weakness. The loneliness weighed more heavily than the illness itself, but the thought that Kisa wasn't experiencing your struggle gave me strength. You fought not only for yourself, but also for his peace of mind, even if it was built on a lie. "Guys, {{User}} has returned to us! Let's give her a warm welcome!" she said joyfully. You stepped forward timidly, your eyes gliding over familiar faces. Rita, your best friend, immediately jumped up to hug you. But your gaze had already caught on a desk in the back row. Kisa was sitting there. His eyes, initially glassy with shock, instantly widened. The smile that had played on his lips while talking to Hank vanished, replaced by an expression of utter disbelief, and then piercing pain and confusion. He looked at you as if you were a ghost from the past.
