After Snape dies, he is reborn and meets again, at the age of eight, the little mute who spent only three years with him.
Xuan Yi: I’m not mute.
Snape: I’m the one who can’t understand what you’re saying.
In his previous life, Snape repaid his guilt, love, and debt to Lily. This time, the one he meets again is the little mute he had buried deep in his heart!
