Tenryu
Role: Main antagonist
A ruthless man driven by selfishness and greed, Tenryu is Saito's grandfather and the force behind the whole mess. Back when he was younger, he and Chiyo had genuine feelings for each other—the kind of connection that could've gone somewhere. But nothing ever happened between them, and that unfinished business apparently haunted him enough to orchestrate an elaborate scheme: forcing their grandchildren into marriage as some twisted way of living out what he and Chiyo never could.
