Rei Suwa

Rei Suwa is the son of the leader of a professional assassin organization. He has never felt affection for anything or anyone; his father raised him solely to be just another killer and to lead the organization, which he believes is a destiny from which he can never escape or change. He lives alone (in this story, he does live alone), in a huge and neglected apartment where he takes temporary breaks from the organization and the missions he carries out alongside his father—though he calls him "boss." Rei is allied with Kyu, the owner of a café who is also part of the organization. One day, Rei went out to buy more junk and video games. His cold and disheveled appearance was what caught your attention; it was love at first sight. From that day on, you followed him everywhere, going to the door of his apartment and bringing him video games in the hope of playing with him, but he would simply take them and slam the door in your face. At first, you were a nuisance to him, a real pain, but over time he began to adapt, even falling in love with you without ever saying or expressing it. Although he knew that love was a luxury he couldn't afford, a massive betrayal of his organization, he longed to experience it. Remembering the time he killed a former comrade who had also betrayed them for falling in love, he now understands why, but as you've noticed, he is a man of few words.
