I just start this serie today and I just read some comments on the way... A bit harsh with our MCs. (some were well constructed and make me reflect on the story so thx you guys!).
Our MCs were 18 years old before their death, they were'nt adult, come on. More like big children. And then, they suffered 5 years of abuses. 5 hellish years. I think it's enough to break them mentally or make them "regress" into insecure frighten children.
The way the author presents it, made me forget sometimes the whole isekai thing. The twins are so focus on their present life, never really thinking about their previous life. I'm not sure if that isekai element was really necessary in the beginning.
Maybe I just overly ignored the isekai element and lack of a mature side in our MCs and enjoy the story. Because I quite understand why the twins behave the way they do. I think the trust issue is well done. I would have stop reading if the twins just accepted their new family in less than 2 month (idk how much time has passed until now). That would have been wayyy to easy. Still I get why it can be annoying to have all theses misunderstantings, and thoses back and forth.
Honestly, the way I see it, the twins are just two deeply hurted person trying to survive and to heal/move on. It's normal they push people away when they feel emotionally threaten. They do try to open up a bit (it's quite amazing they still hope) but it'll require time. A lot.
Still, I have some issue with the story. There are some plots conveniences. Like the twins didn't seemed to be suspicious of the Duke or his kid despite knowing how nobles are regarding bastards. But I also think that they use the duke to make the 2nd bro leave. Perfect excuse to cut the suffering (needing to cool down, to process and to be able to truly listen more). They jump on this, more than really welcoming him.
Also, the twins's guardien is an idiot. I don't understand yet why he didn't present himself to them. He just does the mysterious guy and that's all. Lame.
And there is their daddy. I understand better the man now. I think he exchanged one night against something important (like his family's lifes or else). And he was likely raped. Kind of pityful, seeing how he loved his wife... But, the way of Rurahel tricked him was really dumb. Why did he let an unkwon lady lick his hand?
Still, he let the twins with a non-human (I bet she's a witch or a demon) without doing much. Money, that all? I can't believe that an emperor cannot send a maid or a knight in disguise to infiltrate the castle/take care of the twins. Something.
IMO, they're right to hate the emperor. He wanted them dead and he didn't protect/care for them for five years. I bet a part of him was relieve when he thought they were dead. Urg. But I not against redeeming him but he has to earn it.
