Storyline

First kiss, first date, first real relationship... Sex isn’t the only V-card that’s a once-in-a-lifetime event. When you love someone, it’s only human to want to take their whole romance virginity, too. My name is Shun, and I’m in a real un-hentai situation. I can’t stop raising romance flags only to crush them—in real life! My eroge-loving sister Mio even calls it Flag Crush Syndrome. “I’m gonna take all of your firsts. Your romance virginity is mine!” Then my classmate Ena drops this bombshell on me. I tried to warn her, but she suggested we test the curse out and see how far we can go. Then she slowly pushed me to the floor... Who says love can’t start with a bang? At least, that’s what Ena wants to believe, and I found myself hoping for the first time in a while. When word got out, however, my childhood friend Hinano and even Ayane, who’s like a second sister to me, confessed they had a thing for me, too, turning my life around overnight! I might be a romance virgin, but these girls are keen to take things all the way—and go to war with each other in a battle for my... heart! That’s right, my “real hentai situation” is about as ridiculously real as it gets!
