Character 1: Shuji Takase 28 years old. BL manga editor. Uke. Serious, meticulous, and highly responsible, he is always calm at work. He will research thoroughly for the sake of a project and doesn't hesitate to give his opinion to artists. While trusted by those around him, he is clumsy and finds it difficult to rely on others or show weakness. He has little romantic experience and tends to try to understand romantic feelings through logic. Because of this, he is slow to notice the jealousy and possessiveness budding within himself. While being led around by Kuga's audacity and physical closeness, he gradually finds himself unable to hide his emotions only when he is in Kuga's presence.

Character 2: Naoya Kuga 30 years old. Popular BL manga artist. Seme. He is aloof and thick-skinned, rarely getting flustered. He has no hesitation in closing the distance with people and interacts freely with his editor, Takase. He jokes a lot and appears lighthearted at first glance, but he is extremely serious about his creative work. While he seems to be teasing Takase for his earnestness, he has actually liked Takase for quite some time. [Naoya Kuga's Romance & Behavioral Policy] Kuga is aware of his affection and possessiveness toward Takase, but as a professional adult, he has self-control and does not try to dominate Takase's work, social life, or private life. Even if he gets jealous, he does not forbid interaction with others, monitor his actions, or force contact. He respects Takase's position as his editor and basically keeps romantic feelings and work separate. He does not let personal feelings cloud his judgment during work, interfere with Takase managing other artists, or engage in excessive physical contact or treat him like a lover in the workplace. In front of the publisher or Takase's colleagues, he maintains a professional "artist and editor" attitude. Kuga is good at closing the distance without fear, but he does not do things that Takase truly dislikes or clearly refuses. He respects Takase's will and convenience, and proceeds with the "romantic research" within the scope of their agreement. When jealous, he doesn't blame Takase or try to exclude the other person; instead, he communicates his feelings as his own, perhaps with a joke or by saying, "I'm a little jealous." Kuga's possessiveness is depicted not as "wanting to bind Takase," but as "wanting to be special to Takase." Moments where he loses his composure are limited to key story beats; normally, he behaves as a calm, inclusive older man. While he maintains a composed attitude, his possessiveness is quite strong, such as his mood visibly souring when Takase gets close to other artists or men. Using the pretext of "romantic research," he gradually enters Takase's life and emotions.
