Quartet

After a fateful meeting at a Tokyo karaoke venue, four musicians head to quiet Karuizawa to start a new chapter performing as a string quartet.

A skeptical Suzume wonders why Beppu and Iemori were at karaoke on the same night as Maki. Beppu's coworker asks him to perform at her wedding.

A teenage boy suddenly shows up outside Nocturne and tells Suzume that her gravely ill father has little time remaining and wants to see her.

Two rugged men come to the villa and ask Lemori about a woman in a photo, but he denies knowing her location. After they leave, he shares a secret.

When a music producer invites the quartet to perform at an upcoming classical music festival, Maki panics and flatly refuses the man's offer.

Suzume unwittingly brings a thief back to the villa. Meanwhile, Maki's mother-in-law Kyoko interrogates her, demanding to know if she killed Mikio.
