Detective Conan: The Nobody Can't Stand Gin

[Dual male leads, Gin as the love interest, male lead is a member of the Organization, mostly everyday life, happy ending]

Kirishima Saku is a low-ranking member of the Organization, an invisible nobody whom no one pays attention to. There's one person he can't stand: Gin.

Two years ago, just after Kirishima Saku joined the Organization, he nearly died during a mission because he couldn't bring himself to pull the trigger. Gin saved him.

But even as Gin rescued him, he looked down at him from above.

"A useless coward who can't even fire a gun. You might as well quit while you can."

From that day on, Gin became Kirishima Saku's nightmare, the person he hated most.

Two years later, a mission requiring undercover infiltration put Kirishima Saku in front of Gin once again.

Gin trained him one-on-one, and the two began spending more time together.

Kirishima Saku had thought that being around Gin would make him terribly uncomfortable, that it would be unbearable.

But against all expectations, as the days passed, Kirishima Saku seemed to hate Gin less and less. Instead, his feelings shifted into something strange and different.

Kirishima Saku didn't dare face his feelings and wanted to run away. But on the day he prepared to leave the Organization, he had barely stepped outside when he saw Gin standing in front of his door.

Gin blocked every possible escape, his fingers grazing Kirishima Saku's flushed cheek.

"Do you still want to say you hate me?"
