Real Hentai Situation! DT

Shun cannot stop triggering romance flags only to crush them in real life — his eroge-loving sister calls it Flag Crush Syndrome. Then classmate Ena drops a bombshell: she is going to take all of his firsts, and his romance virginity is hers. She suggests testing the curse together to see how far they can go. Word spreads, and suddenly childhood friend Hinano and even Ayane — like a second sister — confess their feelings too, turning Shun's life upside down overnight. A battle for his heart has begun.
