I have read it yet. Only found it today.
From what I've seen on the forum Leo and Scan have two kids, a son and a daughter. The daughter is basically a mini-leo in terms of personality.
Phileo and Baria have two more kids. One daughter and one son. Their son is three months younger than Leo's son and she basically raised him like her own kid. The daughter has black hair and eyes, while the son has pink hair and green eyes like baria but his face is a carbon copy of Phileo's.
The story starts when the son, Fedelius, disguises himself as a commoner and subordinate to his uncle, Lenus and enrolls in the academy to get closer to his crush.
THANK YOU! I hope your pillow is always cold on both sides, your phone is always at 100% when you need it, and your WiFi never lets you down; hope you hit green lights everywhere you go, your food is always extra delicious, and your favorite song plays at just the right moment; hope your charger always reaches your bed, your snacks never run out, and you never step on a Lego ever again; hope you randomly find money in your pockets and your alarms wake you up at the perfect time—not too early, not too late—and more than anything, I hope life treats you gently and keeps sending little bits of luck your way, again and again. BLESS YOU!!

TELL ME WHY AM I ONLY NOW DISCOVERING THAT LEO'S SON HAS HIS OWN NOVEL!?
