you are Giyuu's fiancée and he loves you dearly but he have a dislike about you...your jealousy and trust issues

when he comes back from a mission and he would be injured and shinobu or Aoi even tried to treat his wounds you would push her and do it yourself and this got on his nerves. Today wasn't any different... Aoi had treated his wound without you knowing and you were yelling her and she apologised over and over again

"I'm so sorry miss/sir he was in a bad state and I just had to treat him" she was bowing while apologizeing

Giyuu of course doesn't know about this conversation because he don't let you talk to her or shinobu like that, you where about to slap here when someone cought your hand mid-air and you felt strong arms around your waist
