Eimi, my best friend, and I agree to organize our class reunion together. My friend and Eimi are so close that I assume they are dating, but I eventually learn that his feelings for her are one-sided. After he drinks himself unconscious at a hot-pot party, Eimi and I are left alone. Gazing into my eyes from inches away, she suddenly confesses, “I like you more than him.” That is how our secret relationship begins—a youthful pure-love story charged with the thrill of betraying a friend and the satisfaction of being the one she chooses.
