Alright, here’s my comprehensive review!
Writing Quality- a solid 7/10, really good, although there are quite a few grammatical errors + small things like ‘phoenix’ instead of phoenix, but those could be resolved pretty easily, and the author actually does it when you let him know in chap comments.
Updating Stability- The first chap was 6 days ago, the novel has 20 chapters. I give 5 stars for updating daily, so extra points too.
Story Development- Surprisingly good. Cliche done right. The only thing im worried about is Arrogant young masters, 6/10
Chara Design- 9, the siblings’ interactions are fun to watch, and the princess actually is interesting.
World BG- There has been close to nothing on it yet, the default I give when that’s happened is a 4/5
