Does no one remember how much of a bitch his sister was?

She was also young and "brainwashed" by the church. Daath had no chance to defend himself because she was told "everything she needed to hear" before he arrived to take her. They were told things would change when they experienced their heat so it would have been easy to twist things to have her think she was being abandoned.
And with all the time that has passed, she has had time to reflect on her actions. She wants to see him as much as he does her, if only to confirm what happened that day.
Saw the very first review from meganekunnim praising the author because she also wrote doctor Elise. I thought I found myself another gem considering doctor elise was pretty good. Story started out pretty meh, got better, got predictable, then got harem-y. Author probably used up all her creative juices on doctor Elise and now we’re left with the sad dregs of story we call capable maid. Wow. I’m sad now.
we are still in the earlier arcs of A capable Maid, I think it is harsh to compare to Dr Elise since that one has more chapters than this...
