Having fulfilled his childhood dream, Kashino Yūki finally debuts as a rookie voice actor. His greatest wish? To perform alongside his childhood friend, Kōsaka Izumi, who is three years older and already a successful, well-known voice actor. Determined to catch up to Izumi, Yūki puts in relentless effort—until one day, his dream comes true. They are cast together in a project…
But the job is a BL drama CD, a genre Yūki has no experience with. Struggling with his role and feeling discouraged, he confesses,
"I just can’t seem to imagine what ‘pleasure’ sounds like…"
To which Izumi, ever the helpful senior, suggests a hands-on lesson…!?
