Saturn and uranus were together.. They both have rings around them, Saturn has bigger..

uranus loves his 27 moons, he treats them like his kids.. well Saturn wasn't too... Happy about that...

So one day in the solar system, Saturn came closer to uranus's moons....saturns gravitational force pulling them towards him... And soon enough.. All of uranus's moons were turned into saturns rings... Only little fragments were left..

When uranus found out he became extremely depressed, and he broke up with Saturn..
