NAME THIS MANGA!

This is a yaoi manga where the guy, let’s name him X is a topper and is really good at studies but he is a commoner. When he was in university he messed by kicking a rude noble who ruined his life as he was the grandson of someone very important and because of him X remained unemployed! Then one day he found a job as private tutor to teach duke’s son. The duke was blonde. His son didn’t liked the tutor at first but he slowly started liking X. X even asked the duke to allow his son to keep a rabbit his pet. In the last episode that I read X was saving duke’s son from two big scary dogs.
I hope I have given enough details. I am trying really hard to find this manga! Please help me! ╥﹏╥
