Also known as: "Did Something Go Wrong? Even After Transmigrating to Another World, I'm Still the Beautiful, Strong, Tragic White Moonlight"
This is the first half of the story. It mainly features a crossover of various series in another world, with no romantic pairing for the protagonist.
Hiromitsu Morofushi should have died. Hiromitsu Morofushi had died.
At least, that was how things had gone in the original timeline.
But a phantom presence calling itself the System changed that predetermined ending. The System said it was the result of the "wishes" of beings in other timelines. Hiromitsu Morofushi made a contract with the System. He would transmigrate into different worlds and "save" someone in each one, in exchange for a chance to start over in his own world and save his friends who had died, as well as himself.
"Host, I'll say it again: whether things can be changed depends on you, not me."
The System's voice was flat, with a hint of helplessness.
The young man with blue catlike eyes smiled, his voice gentle and full of relief.
"But you're the one who gave me this chance."
[Someone's Obsession]
"Didn't you want to write a novel of your own?"
He looked at the young man with reddish-brown hair and gave him a tender smile.
"If you carry kindness and hope with you from now on, perhaps your words can save others, too."
[An Unwilling Self-Sacrifice]
"Why can't you devote your loyalty to yourself?"
He reached out and wiped away the blood-red tears at the corner of the young man's eye. The startling red streak passed over the alluring beauty mark on his face.
"Loyalty isn't foolishness, and it isn't a curse meant for you. If nothing else works, choose to protect. Protect the common people and their happy smiles."
[Kindness Sacrificed]
"I've thought about it for a long time. It seems this really is the only way."
He smiled at the flustered young man, his gaze full of helplessness.
"Stay on the path you've chosen. Follow that person, and keep going without wavering."
[The Reversal of Conventional Wisdom]
"There are all kinds of people in this world. That goes for abilities, and even more so for professions."
He gently ruffled the black-haired young man's hair as he stood on the verge of breaking down, his eyes full of affection and nostalgia.
"All you need to do is be able to answer to your own conscience."
"Congratulations, Host. Mission complete. Rewinding time..."
"Contract complete. Mission 0209 concluded. Unbinding successful."
"A reminder: you have only this one chance, so please treasure it and think carefully. May you and your friends live safe and peaceful lives."
