oh my god what a charmer of a voice

Akari, a 30-year-old office worker, is troubled by her lack of male experience. One day, she discovers that Yanagida, a junior colleague who is famous for his quietness, actually has a good-looking voice. She is very excited when Yanagida-kun, whom she thought was quiet, starts to sweetly come on to her with a low voice...and she is very nervous!

This is an office love story where you will be sweetly loved from the ear by a younger man!
