No matter what woman you throw at rimuru he will always look at shizu first even while she is dead she is all he thinks about In fact shizu is one of the only women whom ciel approves of for her master (cause shizu helped create ciel using degenerate) ciel despises chloe for stealing rimuru's first kiss and will not accept her as a significant other for rimuru Chloe will have to win over ciel if she wants to date rimuru and because of what she did that will be a challenge 😅
