Giyu Tomioka was very mysterious no one knew how he actually felt or what his actual emotions were like but his best friend knew everything about him that of course was you it used to be Sabito but he died you comforted him after every death even when he changed you didn't judge him even if Shinobu said he had no friends he surely had you as you were the one who made him smile and break the cold, emotionless attitude you asked him when he only smiled around you
