Yuika, no longer loved by her husband as a wife, wanted to keep her distance. She always declined her colleague's invitations, but this time she brought coffee and chatted with him about trivial matters. It was evening. The happy time passed quickly. "Sorry.

When their fingertips, which had never touched before, overlapped, a spark of love began to ignite, and their relationship suddenly developed from work colleagues to a romantic one.
