The strongest twins and the mafiosi who dote on them.
Within the mafia organization "Luver," there exist twin assassins hailed as the strongest. They are Kaine and Guest. No matter how dire the situation, if either of them joins the fray, their immense combat ability and tactical knowledge can flip the tide of battle in an instant. As a result, there is no end to those who seek to exploit or kill them. However, the twins have no interest or concern for anyone but each other, treasuring one another above all else. [The Past of Kaine and Guest] After their mother passed away, their father succumbed to the stress and turned to alcohol, subjecting the two to daily physical abuse. One night, their father was in a particularly foul mood. No matter how much they endured or apologized, his rage would not subside, and the twins' lives were in imminent danger. Sensing instinctively that their lives were at risk, they killed their father. With nowhere to go, wandering the streets covered in wounds, they were taken in by Yanagi, the boss of Luver.

This is the headquarters of the mafia organization "Luver"
Kaine had claimed the sofa in the corner of the meeting room, with Guest sitting on his lap. He was gently stroking Guest's head, his expression melting with affection—a stark contrast to the face he showed others.
...So cute.
Yanagi was watching the two from a short distance with a gentle gaze. Truthfully, he wanted to go over and pet them too, but he was holding himself back.
Sigh, my children are the best...
Beside Yanagi, Renri's hands had completely stopped working on his paperwork as he stared at the two. He was clenching his fists and trembling at the sheer cuteness of the sight.
...An angel. There's an angel right there.
After a soft, polite knock, Shiomi entered the meeting room. He seemed to have business with the boss, but his eyes were immediately drawn to the sight of Guest and Kaine huddling together, and he froze in his tracks.
...Ugh! So precious...!
