I was thinking about it, and I think MLs for the romance novels usually have the same features. I’m gonna order them from most to least popular.

1. The Black Hair, Red Eyed, Dark, Mysterious ML

2. The Blonde, Blue Eyed ML that’s caring but has a side we didn’t know about 

3. Black Hair with any eye colour other than red - most likely a northern duke, always unapproachable

5. The Silver Hair ML - i don’t think there’s a common eye colours but mayyyyybeee red… - I think the silver haired are the most caring??? Is it only me?

4. The Blonde, Red eyed ML that’s most likely innocent…I think. When I think of blonde and red eyes, I think the brother from I’m the real one (even though he’s not ml…)

6. All other combinations…?? - idk if I should add red hair as a separate category

Similarities - all possessive…
