Black-aligned true liquor + two male leads, both devoted to each other + breaking the loop + not a native of this world + amnesia trope
Svitlan is actually arrogant and conceited. He deludes himself into thinking he can protect those close to him.
His colleagues, mired in darkness, mock him: "Stop losing it. Everything here is perfectly normal."
His abandoned lover pleads with him: "Please don't hurt yourself, okay?"
An emotionally charged scent lures him in. That gentleman says: Svitlan's nourishment is flesh and blood.
"Eat me, ■■." The person before him cuts open their skin, the scent of blood rushing into his nostrils as they pull Svitlan into their arms.
Svitlan is not weak. His disordered perception will not stop him, and post-traumatic stress disorder will not kill him.
But Moskovskaya still has room to grow. With guns and bullets, lips and teeth, whether in a fight or a bite, the enemy will die before the ending arrives.
Take a deep breath. Even a good little tool has the right to enjoy happiness.
What's suspicious about the little boy who keeps appearing at crime scenes?
He has no memories, yet there are records of experiments. Which one is real?
As time returns to normal, is he heading toward the light or sinking into the abyss?
The less serious version (sorry for the OOC)
Svitlan: I got "kicked out" of the organization, so why are you still watching me? Stop barging in on my time off, dammit!
Codename members: You're the one we're after.

Oh, most merciful old world, welcome home the bird returning to its nest.
(I don't know the original plot. The police academy team survives. No System, and the protagonist isn't invincible. Characters may act dumb.)
