Reformation of the Deadbeat Noble

A brief description of the manhwa Reformation of the Deadbeat Noble:

Young Irene Pareyra made his dream world a refuge from the pain of the tragedy of the past. People were amused by this, they made fun of him and called him a careless aristocrat.

However, this attitude did not touch our hero in any way with the need to change.

This would have continued if he had not met in a dream a talentless young man who had been learning to use the sword for thirty-seven years in a row and died with a weapon in his hands.
