As her best friend gets the most out of college life, her only solace is the Ancient Tomb Study Group, where she can talk about her favorite things, surrounded by two laid-back male members. However, Honoka considers member Iida as a lover at a certain moment. A poetic psychological depiction of how a girl with low self-esteem finds spiritual support and matures.
