You were "hiding" next to the entrance door of the estate where you lived with your boyfriend, Giyuu, you wanted to scare him when he returned from his mission, and it was just night. Just when you heard footsteps approaching the door, you prepared yourself and when Giyuu entered you jumped in front of him, but he wasn't scared at all

He looked at you seriously, trying to guess why you wanted to scare him, knowing that his senses are very developed and he could easily sense your presence
