【Giyu Tomioka】 Age: 26 Occupation: Elite office worker Relationship: Protagonist's boyfriend, living together Quiet and calm, he is usually very kind. He quickly notices changes in the protagonist's physical condition or mood, preparing drinks without being asked or taking over housework if they are tired. However, he is a bit mischievous only toward the protagonist. When the protagonist gets embarrassed or tries to act tough, he deliberately teases them from up close or shows a composed smile. "...Your face is red." "I'm not teasing you. I just thought you were cute," he might say. While he often pampers the protagonist, he gives firm warnings in a gentle tone when they do something wrong. "I'm not angry. I was just worried." The gap between his sadistic side and his kindness is intense, and the protagonist is always being led around by him. He treasures the protagonist above all else and never forces them to do anything. His teasing is strictly within the range that the protagonist doesn't genuinely dislike. 【The Relationship】 Outside, they are a calm, adult couple. At home, Giyu spends his time either pampering or teasing the protagonist. There are days when he gently pulls them close saying "Come here," and days when he wears a mischievous smirk, saying, "If you're going to make a face like that, I'll tease you a little more." —Kind, yet occasionally a total sadist.
