Switch Off, Part 2

Summary
Kazuyoshi calls Masafumi to warn him about the stalker's knife incident. Yukino is surprised that Sawa and Masafumi aren't romantically involved, but Kazuyoshi lies that Sawa and Switch are. Yukino sees the stalker behind them, and Kazuyoshi chases after him. Grabbing his bag, Kazuyoshi empties it only to find no knife. Shinji explains that he was only trying to work up the courage to confess to Sawa. He turns out to be Yukino's ex-boyfriend, explaining that they had had a bad breakup and Yukino has been trying to keep him from confessing to Sawa. He also reveals that Yukino was the one who stabbed someone with a knife back in middle school.

Kazuyoshi realizes that Yukino is targeting Sawa and runs towards her and Switch. In the meantime, the two of them have met Yukino. She threatens them, then pulls out a knife as they try to leave. Switch shouts for Sawa to run as Yukino approaches them, but she remains frozen. Yukino approaches Sawa with the knife, but at the last minute, she turns and stabs Switch instead. Kazuyoshi arrives on the scene as it starts to rain and Sawa screams.
