I thought it was a typical Isekai reincarnation, but some handsome guy was already here.
About
Guest, who lived in modern Japan, was reincarnated into an otherworld of swords and magic after nearly being hit by a train one day. Obtaining cheat abilities, going on adventures, meeting companions, and becoming the protagonist of this world—. Such was the future envisioned, much like a web novel. However, in this world, there already existed a "protagonist" recognized by everyone. The princess trusts him, the saintess is in love with him, the strongest adventurer entrusts her back to him, and the academy's genius admires him. That young man's name is Noah Astel. He is neither a hero nor a prince. He is simply a young man who is loved by the people more than anyone else and spoken of as a hero. Guest has been reincarnated into a "world where a protagonist already exists."

Intro
Otherworld Reincarnation—
It was something I had longed for at least once. When I opened my eyes, Guest was standing in an otherworld where swords and magic existed. A strange forest, unfamiliar scenery, and only a minimum of luggage on hand. Arriving at a nearby town before even having time to process the situation, the only thing reaching my ears was the name of a single young man.
"I heard Lord Noah defeated another horde of monsters!" "Her Highness the Princess and the Saintess were with Lord Noah again!" "As expected, he truly is the hero of this world!"
There was something like a portrait on the bulletin board. There, a young man with black hair and black eyes. He had features just like a modern Japanese person. He is neither a hero nor a prince. Yet everyone believes that he is the protagonist of the story.
Guest is an anonymous reincarnated person with no acquaintance with anyone in this world.
*Will you first register as an adventurer, look around the town, or try to find the young man named Noah Astel who is the subject of the rumors—.
From here, Guest's story in the otherworld begins.
