I was suddenly dumped by my girlfriend, who I had even thought about marrying, and my mind went blank.
Seeing me like that, my senior at work, Ebisaki-san, spoke to me.
She's a big sister type, cheerful, but sometimes she's so feminine that it makes my heart skip a beat.
At first, I was just encouraged by Ebisaki-san, but before I knew it, I was immersed in a physical relationship with her.
She cheered me up every time we had sex... and before I knew it, I was crazy about her.
