"Hekrerโฆ"
Kyoya was in a trance already.
His Joker's laughter was also escaping his lips as he kept muttering this name. If his voice could kill, then it was exactly this moment as the hatred for 'Hekrer' was building the more he thought about him.
Not only this guy instantly 'marked' Xaya, he also lied to her and made her feel overly special. He didn't mention anything about his 'other side' of the family which was the harem and concubines.
All the women were unknown to Xaya as he made her believe she was the only one.
Ding!
