Rose Tyler was not usually one to be selfless. Spending most of her life with her mum, she had come to get whatever she wanted.
For the sake of the universe, however, Rose was selfless. She hid a secret from the man she loved, so each and every universe would be safe. She couldn't let him destroy the universe because of her. No matter how much Rose wanted to be with her Doctor, she couldn't risk all life just to save her own. In saving all the universes and species alike, all she could feel was guilt.
Rose Tyler had told a lie.
An awful lie to the man she loved.
She refrained from speaking the truth, despite how much her heart longed for the honest words to leave her lips.
She never told the Doctor about the baby.
The Doctor could not be the man he was before.
He could not be kind, could not be compassionate.
He was merciless, drowning himself in his own sorrow and hate. For the first time in hundreds of years, the Doctor had opened his heart. Loving Rose was the best part of his life, and loosing her was his worst. Just as he had lost those he cared about before, he had also lost Rose. No matter the promises he had made to himself and to her mother, her fate seemed inevitable. She was sealed in a Parallel Earth, where she couldn't be reached, not without destroying everything else. The Doctor had always been selfish, running away to far off planets and having adventures, but this time, he was not. The only thing keeping him going was his knowledge that Rose was safe. At least she was safe.
"Save Bad Wolf." A single message displayed through all of time and space, across endless boundaries, and walls between worlds.
Rose Tyler was not safe.
Rose Tyler was dying.
And she wanted- no, needed- to see her Doctor one last time.

Kanda Kyoichi transmigrated to Konoha and became a temporary instructor at the Ninja Academy. Fortunately, he awakened the Mentor System.
By teaching others, he could earn rewards.
Thus began Kyoichi's career as a "teacher" in the ninja world.
Shisui: "Sensei's unique interpretation of the Will of Fire has given the Uchiha Clan a true sense of direction!"
Asuma: "The essence of the jade lies in protecting the people, with the advanced leading the way for the less experienced. Only then can Konoha become stronger!"
Kakashi: "He's my life mentor. He transformed Konoha!"
...
Years later, in the memoirs of Kyoichi, now the Hokage, he wrote:
"I honestly just wanted to be a life mentor!"
