He hated him for seven years, loved him for two hundred years, spent two hundred years to miss him, and was lonely for two hundred years. After rebirth, he only hoped that he could live. He traded with Merlin at the cost of his health, and did not hesitate to be misunderstood by him. He carried his love and flesh and blood alone to the end, and disappeared after the war.
He protected him for seven years, turned into a ghost and hid in the tombstone for two hundred years.

After the war, he disappeared in front of him, and the dusty memories were awakened, and he searched frantically.
He spent seven years being hostile to him and had been his friend for two hundred years. One year after his death, he returned to the past. He watched his best friend suffer alone and in pain. He watched his godfather forget and search. He thought he would never meet again.
Eleven years after the war, at the Hogwarts freshman sorting ceremony, the appearance of a pair of twins gave them hope again. It turned out that he had never left.
