Hikari (light) is a short, childish, and emotional girl.

Hibiki (sound, echo) is a tall, quiet, and shy boy.

One puts their heart out often, while the other doesn't do it enough.

All Hibiki wanted to do was finish high school and leave for college to live the life that was planned, he didn't expect a small girl continuously talking to him like he was actually someone special.
Hikari was naturally a caring person, seeing someone alone made her feel like she had to step up somehow, it was just the kind of person she was. She didn't expect to make much progress quickly, but she was surprised easily.
