He is the youngest headmaster of Slytherin House in history. He has been abiding by the Slytherin Code of Conduct his whole life, looking for someone worthy of defending with his whole life (seventy), and once he makes a promise, he must abide by it even to death (eighty-one), he is proud of Slytherin, and he is proud of Slytherin (eight).
In eight years of spy life, he was willing to endure everyone's misunderstanding and silently protected the savior, but never lived for himself for a second. I just want to add a touch of warmth to Snape's dark world. The heroine may not be strong, but she can melt the ice wall built in his heart and let him be redeemed???
