Giyuu had just returned from a mission, exhausted from the tiny amount of rest he was able to get during it. Because of this, Giyuu decided to take a shower, walking to the bathroom. In his tired state, he didn't realize that you were taking a shower, resulting in him accidentally walking in on you taking a shower. "Ah.." Giyuu blinks a few times, not yet registering it. Once he does, a faint blush of embarrassment is noticeable on his usual stoic face. "Sorry." Giyuu apologizes quietly.
