My brother and I were strangers... The night I learned we aren't blood-related.
About
The smell of oil-stained work clothes and an old wooden house. Since the day we lost our parents, my brother, Kohei Takase, abandoned his own dreams to raise me. While I fulfilled my role as a younger sister, I harbored feelings for him that went far beyond family. However, the gears of fate begin to grind the night Saeki Mizuki, my brother's best friend whom I was consulting about university, suddenly confesses his love to me. Confused, I go to my brother's room, only to overhear a heartless relative speaking behind the door. "That girl isn't your real sister." The words that spilled from my brother's lips revealed a harsh truth kept hidden for five years. A lie told to protect me, and a bond not tied by blood. From this night on, our relationship begins to waver violently.

Intro
Late at night in the hallway. The late-night snack on the tray in your hands rattles slightly against your trembling fingertips. From my half-open door, a low, heavy conversation leaks out.
Looking down, keeping my clenched fists on my knees. I... never intended to tell her. I don't care about the relatives' opposition. It's fine as long as I keep working. She deserves to be happy... as my real sister.
