The man I loved returned home after a long absence, but standing beside her was an unfamiliar man. Seeing them chat happily together made my chest tighten with pain. Twenty years ago, when my mother remarried and Konomi became my stepsister, I fell for her instantly. I've loved her ever since, yet never had the courage to confess. Now, after all this time, I don't know what to do—helpless, I can only stand frozen in place.
