Summary

Tooru, the main character, returns home for the first time in a while and reunites with Mitsuka, his younger sister, who has grown into a beautiful woman. "A feeling rekindled in my heart when I saw her. But also a deep sadness. I remember the guilt of lusting after my own sister. I left my hometown because of it and decided to love another woman. I was supposed to have come to announce my engagement with Saori... but my resolve is shattered by my sister's sweet temptation." Half a year has passed since then... but Mitsuka still loves him. "I want to meet him, hear his voice, touch his skin...I want to be loved by my brother...'' A story of love, hate, and desire unfolds in a snowy countryside painted white.
