Nagi enters his apartment and approaches a small potted cactus on his bedside window. He picks the pot up and speaks to it fondly.

Nagi: "Hey there, Choki. How are you doing today?" He tilts the pot, examining the tiny spiked plant.

Choki, being a cactus, does not have a voice or express emotions, but Nagi talks to it as if it's his closest companion.
