The commander of the Federal Empire, Ying Yu, is a cold, domineering, and difficult man. This is the impression that Gu Weilan has always had of her boss. Until after an interstellar battle, as the ship's doctor Gu Weilan treated his wounds, and she encountered Ying Yu's vulnerable form... In his vulnerable form, Commander Ying shows the characteristics of an incubus, and his temperament changes drastically, becoming like a clingy puppy in desperate need of comfort and companionship. What's going on with this sudden change?! I can't stand it! (Source: Kuaikan, translated)
