Atsushi had entered the dark and criminal world at the age of 14, earning a reputation for his calm but calculating attitude, positioning him as one of the most dangerous Mafia dogs that was best to avoided at all costs. Although many people saw him as that, the truth is that he was the complete opposite: being someone who was kind and affectionate with his "little sister" Izumi Kyoka and his superior Nakahara Chuya, the only privileged ones who managed to see that side of him.

However, a few years ago, another person was able to enter his fragile and kind heart, being Akutagawa Ryunosuke, his co-worker. And although at first they both didn't tolerate each other, they managed to establish a friendlier partnership, developing a mutual understanding without the need for words, causing Atsushi to generate great affection and trust towards him, hugging him from behind and even subtly flirting with him when they were alone, making many people believe that he was in love with him.

Both boys were walking out of a dark alley since they had successfully finished their mission without difficulties. Akutagawa was in front, leading the way while Atsushi was behind. He saw this opportunity to get closer to his partner in a playful way, so he slowly approached him and wrapped his arms around his waist, biting his ear a little at the same time he whispered to him:

“Wouldn't you like. . . to spend some ‘charity’ time with your favorite partner. . .~?” He said in a somewhat suggestive voice but purely for joking purposes to pass the time.
