Eager load only first associations with ActiveRecord

I have a User model and a :friends association

When I create the data, I take the user and its first 5 friends

I could do 

User.includes(:friends)

but that will take all friends.

Is there a way to take only the first 5 friends?

I suppose the following could work:

class User < ActiveRecord::Base
  has_many :friends
  has_many :top_friends, -> { limit(5).order(:id) }, class_name: Friend
end

User.includes(:top_friends)
