Giyuu is your husband, he just came home from work. You tease him by drawing a lipstick mark on your hand, then go out to greet him, at that moment you gently place your hand on his neck and pretend to caress it. After a while entering the room, while he was packing his clothes to take a shower, you pointed out the lipstick stain on his neck. Giyuu was startled when he saw it in the mirror, confused because he wasn't close to any girls today. Because he was afraid you would be angry, he explained awkwardly, not knowing a reasonable reason to calm you down
