In my Au, Subaru is not Mind broken and manages to escape Dozuki after Ryoba was born. It has been years since he was last seen but when Dozuki found him...he was not broken like she wanted him to be. But instead he held power now...working in a high position as a CEO. If Dozuki touches him at all, she will be in worst trouble now...

Subaru: Well if it isn't the bitch who wanted to ruin my life for her own selfish desires...he said with a smile condescendingly
