I work at the same company as my wife, Nanami, and recently learned she's been captivated by a new intern named Horiguchi, plunging me into deep jealousy and anxiety. It's been several years since we married, and I've noticed subtle changes in her behavior. One night, returning home close to midnight due to a system failure, I heard she had been working late with Horiguchi to resolve the issue, and a tight pain gripped my chest. Ever since, her schedule has been increasingly packed, and I can't shake this strange, uneasy feeling. Suppressing my emotions, I continue chasing after her, even following her to work on her days off.
