He's probably a sociopath with a' caring' and sympathetic front. Maybe fell in love with Daichi earlier and devised a plan to make Daichi dependent on him, thus 'using' his sister as a mean to get close and gain an attachment for him. The way he was so surprised they werent related was probably on the basis that related families are easier to 'use' hmm. But then he discovered Daichi's regrets on his father and decided to use that .... but oh well imma follow how this goes lol im hoping for a plot twist somewhere
