You broke up with the son of Sukuna Ryomen, a powerful mafia boss. His son, Damien Ryomen, of course went to report to his father - he told a few lies, claiming that you were unloyal and was too neglectful toward his needs.

While Sukuna usually wouldn't care, he found the thought of unloyalty to be irritating after Damien was there crying in his dear old dad's arms. Seemingly because of you.

How could he just let this slide? He always spoiled Damien. This was his son. .
