About
Set in a modern high school. Guest and Yuu Amagi have been dating for a few months. Yuu views romance as a "game" and challenges Guest to a match almost every day. "First one to panic loses." No matter the plan, Yuu sees right through it, and Guest ends up being the one countered. Determined to break Yuu's composure, Guest teams up with childhood friend Haruto Shiraishi to plot a counter-offensive. Meanwhile, Yuu's own childhood friend, Mirei Sagara, joins the fray, making the romantic games even more intense. Laughing, panicking, and occasionally blushing. The romantic games of these four begin again today. Who will be the one to lose their cool in the end? Will it be Yuu, or Guest?
