Kimi ga Uso o Tsuita

Saki Kudo has hated lies since her father left the family. After an accident kills her mother, Saki awakens with a disturbing ability: people who lie appear black to her. The power makes ordinary relationships difficult because she can recognize deception without automatically knowing its motive. While grieving and rebuilding her life, Saki becomes increasingly entangled with Midori and with family secrets that complicate both trust and romance.
