The plot is really good. But the progression is way too fast. It's boring when it's just the mc being op all throughout the story. It can be dragging. Same for the girls. I wished that the mc didnt have his previous powers and slowly activated them as he grows older
And also did they just plan for the dragon girl to be looking young for the sake of the loli harem concept?
She's supposedly over 5000 years old. I get that she hasnt transformed before. Maybe that's another reason

the secret behind magical existences like magic creatures and magic objects always turning into loli human forms was revealed here: http://www.mangago.zone/read-manga/sokushi_cheat_ga_saikyou_sugite_isekai_no_yatsura_ga_marude_aite_ni_naranai_n_desu_ga/mdx/mpn_chapter-2128949/pg-15/

I just wanna point to everybody. because there is a lot of comments how the male lead was such an asshole and betrayed the female lead. and don't want them to end up together. I do agree that helt made some wrong choices but
Kaid did it for the country. the citizens were abused off their rights. the royal family were abusing their powers.
but why did he had to kill the princess? she was given the chance to survive but one of the big reason is that she has the blood of the the former royal family. the citizens won't be able to live in peace knowing that the bloodline is still there. that's why the public execution happened.
Why did he lie to shirley? from my perspective. everyone in the castle wants her to remain her happy and cheerful self, not knowing the ugly world. she was loved by the servants. and also this was a really important mission for Kaid which could risk the country
Why did she had to go back and serve Kaid? why not just leave her alone and live her life? it's to reassure her by everyone that it was not her fault. she need the reassurance and to get rid of her thoughts that she must pay for her family's sins even though she reincarnated. they want her to live happily with her own dreams and not be tied to the past
(Some are explained by Fuyukuchi and criticalrx in the comments.)
There are times that when I think that Shirley and Kaid should not get back together too but..
SPoiler*
in the novel, They were going to separate. kaid did not forced her to stay. they talked to each other about this. but because of circumstances in the end she decided to stay.
The author did a really great job with the flow of the story and shirley's character development. which is why i love the novel so much

I seriously want more extras solely for yashiro and megumi.
I love this couple so much ε=ε=(ノ≧∇≦)ノ

It may be this one:

I do too, it reminds me of my Lolo and Lola. I’m going to bust down in tears cause of how relatable this is.
