The protagonist, Ano, had a childhood friend.
His name was Jin.
Jin was a modern god (arahitogami) with strong divinity, reverting from his ancestors.
In this world, modern gods are worshiped as sacred professions, and Jin was famous due to his appearance.
However, due to his naturally gloomy personality, he was kept at a distance from her since long ago.

The protagonist had never thought of Jin as a member of the opposite sex, but he confessed his feelings to her and they started dating. Their
relationship was generally going smoothly considering they had developed from childhood friends, but Ano had one problem.

That was that Jin would come on to her with great force whenever they were alone.

That day, the act escalated more than usual, and the protagonist tried to stop Jin.
However, Jin's "word spirit" made the protagonist climax by force at the entrance.

The protagonist had tried to avoid meeting Jin for a while after that, but suddenly saw Jin on a monitor in the city.
Jin being interviewed as a living god felt like someone from a distant world.

(I'm not a good match for her...)

"I wonder if we can go back to being childhood friends,"
the protagonist tells Jin after much deliberation.
However, those are the words Jin least wants to hear.

"It's only thanks to Ano that I've been able to be like this."
"Don't say things like that to push me away..."

The protagonist notices an ominous presence from behind Jin.

"I've thought of a way to stay with Ano forever."
"Huh..."

"I just need to hide Ano."
