the favor was to make this ring..and then he asked to cancel the order cause they broke up..but the ring was already made that's why the brother gave it to shingo..as why he asked the brother to make the ring is because the brother owns a huge jewlery company..
I'm not quite sure about the ring. Did Kagami told his brother to cancel giving Shingo the ring but the brother give him anyway? What was the canceled favor? I don't get it, he treat Shingo so bad and cold at the apartament and then he gives him a ring? Don't understand this part.
