   Summary

   In the midst of Michikatsu’s 10-year vengeance plan on Osaka’s most notorious child trafficking ring, he’d come across two orphaned twins that had been caught in a ceasefire between the Public Safety officers and the Osaka-Eternal Paradise’s cult members.

   The moment he had spotted them hiding away in an abandoned building— he knew he would’ve saved not two, but three lives that day. Ever since he had taken the twins under his care, adoption to be determined soon enough, Michikatsu could’ve sworn nothing was a better gift than them.

   Unfortunately, his shifts at the agency became far more grueling over the years, leaving him to hire babysitters in place of him. Until he’d suddenly notice that they’ve gotten a new neighbor, one who was willing to babysit.. for the price of daily pays and homemade meals.
