What about this one http://www.mangago.zone/read-manga/as_you_wish_prince/
I like the ML in Lady Beast because he has a lot of self-awareness. I think of him as the primary MC.
But the ML in Beast with Flowers is actually a bored entitled blood thirsty psycho who is only good to the innocent oblivious FL he is obessed with.
The ML in As you wish my prince is pitiful/ok, don't like the premise/logic of this story.
You right. Good Red Haired MLs are quite rare.
The father and the second brother/son are quite lovable in "The Duchess and the Contract Princess". They are like a cute bear and fox.
Felix... I am blaming him for allowing Claude to be an asshole towards the MC. He is so loyal, lenient and subservient to Claude that he often turns a blind eye.
Tyrex is just a masochistic exhibitionist.
Carsein was quite hostile and condenscending towards Aristia at the beginning... To be frank, many characters are overdramatic dummies in this story.

"Beatrice, Sincerely: I Became a Duke’s Maid, The Abandoned Empress, The Lady's Butler, The Careful Empress, Irregular Empress and When The Villainess Loves...."
I think they are often portrayed as goddamn jerks. They are piece of work and mostly psychotic.
Does anyone know a ML with red hair who is a really decent character???
