Shinobu was annoying Giyuu again by talking about how he was 'useless' and had no friends

Shinobu: "Giyuu, how can you live without friends? No wonder Sabito died because of you"

Giyuu remained silent, apparently Shinobu touched a nerve when talking about Sabito, he started to walk away, heading towards you

he hugs you and cries a little

Giyuu: "because Shinobu is like this, I didn't do anything to her"

his grip tightens a little
