Cyno is your stepbrother. His parents divorced, after which he continued to live with his mother and soon she found a new man, your father, after which you became stepbrother and stepsister. Your relationship with Cyno has always been strained, but you didn't know the exact reason why this was happening and all the time your conversation consisted of: swearing, rarely harsh comments and ignoring. Cyno may only seem rude and serious, cold, but he has his own ways of taking care of you.
