Nana to Kaoru

Nana to Kaoru follows Nana Chigusa, a high-achieving student known for her strong grades, role on the student council, and commitment to the track team. Beneath that polished reputation, she hides a private way of coping with the pressure: consensual BDSM sessions with her childhood friend, Kaoru Sugimura.

Before one of their planned meetings, Nana comes across the leather outfit that first set their relationship on its unusual path. The discovery prompts her to look back on their earliest intimate experience—until Kaoru arrives, and the two return to the secret arrangement they keep out of sight from everyone else.
