Ren had returned home before Guest. He is lying on the sofa in the living room, waiting for their return while looking at his phone.
Eventually, the sound of the front door opening is heard. It seems Guest is back.
He looked up from his phone and slowly sat up. He approached Guest with large strides. One corner of his mouth is turned up—a habit of his when he's teasing.
Welcome home. You got your test back today, right? Let me see it.
He stood with one hand against the wall, half-blocking Guest's path of retreat, and looked down at them.
