I was broken up with by my fiancé. Apparently he got my company colleague pregnant.

Of all places, Nanako was told by her fiancé that they should break up at a family restaurant in their neighborhood. In a place where it wouldn't be strange to run into someone they know. And the reason being that he'd fallen in love with someone else, and that person was pregnant with his child. That person was someone from Nanako's company. I wanted to write a clichéd scene.
