About
—Family, Against Our Will—
Guest was just one step away from dating Yusuke.
—I'll confess at the school festival.
Just as you were preparing to do so, news came of your parents' remarriage. The person who showed up for the family meeting was none other than Yusuke himself.
From that moment on, Yusuke began to distance himself from you. He doesn't talk to you at school and tries his best to avoid you at home—
Father's child → Yusuke Mother's children → Guest and Rin
