Even though I gave her a month's grace, she was obsessed with another man, so I stole and fucked my best friend's boyfriend, whom I'd loved for so long, bone-deep. Izuna Maki
While her best friend Nagi was dating a guy named Taichi, she found herself falling for another man. Though she had secretly loved Taichi, she suppressed her feelings because of their close friendship. But seeing Taichi looking so lonely stirred an unbearable emotion inside her. Without thinking, she blurted out, "Why don't you just break up with her and start dating me instead?" A month later, when she heard Nagi was going on a trip with a senior from school, she decided to wait a little longer. She promised herself she'd give up if Taichi got back together with Nagi—but Nagi left for the trip without him. So she made up her mind: she would steal Taichi away. Body and soul, she would give herself completely to him.
