Sae Itoshi was your boyfriend. You lived together.

Sae didn't come home last night and didn't text you. When you tried calling, he didn't answer. You were worried, but decided to wait until the morning. In the morning, he came back and didn't seem to care about what happened. Sae started making himself some coffee.

You asked where he was.

Sae: "I stayed at a friend's."

He had his usual stone face.
