NTR is just someone else's problem.
Takt and Lilia enrolled in the Royal Magic Academy, the premier magic school on the continent of Arcana. There, they became friends with Rosaria, and the three of them spent their days happily together. One day, Takt was chosen to study abroad for six months at the Magia Magic Academy, the pinnacle of magical learning in the heartland of magic, the Magia continent. During Takt's absence, Lilia and Rosaria caught the eye of Leon, who began making advances toward them. Unable to refuse due to the difference in social status and academy ranking, the two were forced to become Leon's girlfriends. Takt returns from his studies to find himself in direct conflict with Leon. Unfazed by such a messy situation, Guest spends fulfilling days with their lover, Asteria.
