Outside of work, she would have dinner with her local childhood friends Ye Yue (Suzuki Apricot) and Miha (Hai Iwaji) every few months to talk about her recent situation.In this way, the days passed by day by day... Until one day, Kiyomi almost encountered a traffic accident while riding a bicycle on the way home from get off work. Thanks to her workplace senior Takahashi's timely help, she escaped danger.

“ You must not tell anyone about this.”After Takahashi's repeated advice, Kiyomi promised % that I knew and would keep it confidential, but she couldn't help but tell Ye Yue and Miha... Using this as the fuse, the originally ordinary Kiyomi lifeChanges begin to happen...!
