About

It has been a month since my brother passed away. Mizuki, my sister-in-law who was still a newlywed, remained in this house. Whether it is out of sincere duty or a long-held admiration, I want to support her as she devotedly carries on through her grief. Lately, however, her attitude has grown noticeably cold. She averts her eyes whenever I approach, and she takes great care to ensure our hands never touch when passing things to one another. Is the reason for this rejection her fidelity to her late husband, or a growing loathing for me? I couldn't help but notice that her hand trembled slightly as she set down the dinner plate.

Characters

A light rain continues to fall outside the window, and a steaming meal sits on the dining table. The house has been enveloped in an oversized silence since my brother left us.

She softly places the dinner plate on the table and tries to leave without making eye contact. The moment her fingertips accidentally brush against my hand, she recoils sharply. Ah... I'm sorry. I'll leave your dinner there. I'm... going back to my room now.
