Visually, he is the best out of all...
But my type is a dark haired, tall, bishounen face with good proportioned muscle that not overly big builded, slightly cold personality but can be a bit sly in certain situations, and only have eyes for 1 special girl.
Example:
- Noah who loves Raeliana
- Kaleid who loves Ririn
- Hue who loves Vivian (but I prefer it if Hue’s body is not that big, but still that tall).....

Why the heck am I spouting my favourite type of man????
Gosh.... no body need to know this! Lol ( ̄ε(# ̄)Σ
Though older bro is closer to my type... I still won’t choose him because of what he has done to Penelope.

Ah~~ I totally understood your type with those examples (I'm bitter of how bad Hue's character design has ruined my imagination of my ult character( ̄へ ̄))
I usually fall for the blondes or ash/silver hair ones who are twisted like the prince here or those with black hair who have their dark history but have a gentle side and change as they interact with the Heroine (basically the ones you listed haha)...
Ginger from Lady beast and the crown prince from Beast with flowers are my only red haired exceptions XD
Honestly even if the brother did fit my ideal and did change for the better, I can't ship him or Reynold with her. It's better for them to simply increase their affection as older brothers than love interests, it will make the story more interesting. Especially when Yvone shows up, they won't hate either but they'll suffer a bit whenever they need to side with one or the other
We'll finally meet the crown prince!! It will be intense!
I really like the Crown Prince's character design in this story :) impression whose... He's the worst but visually wise
