And the dynamics can tell (Patreon)

Meet Charlie (Dani's older sister) and Mateo (Robin's little brother). Thay will be important characters to the plot that I wanted to introduce now.

Dani is the little one of his family, Charlie is 3 years older than him and just graduated Law school.

Mateo is 2 years younger than Robin, he's Robin's little brother by his father, but their mom had another baby recently. So now he's the middle child of their family.
