Ever since I joined the company, senior colleague Ishihara has trained me and supported me whenever I needed help. She is beautiful, capable, and kind, and my respect and admiration for her have gradually turned into love. But I am still inexperienced at work and lack the courage to risk our current relationship, so my feelings go nowhere beyond stolen glances at her carefree smile during breaks. Then I accidentally hear that she plans to leave the company to get married.
