After an eventful first semester at Luster Magic Academy followed by a busy stay at the royal palace, Yui is back home on summer break! Though she wants to spend the summer researching magic and eating sweets, she's required to attend a school training camp with a bunch of stuck-up nobles who resent her for being there. Influential figures from all over the kingdom have come to observe the camp, and after she shows off her skills as a Liefe in a magic battle, Yui will have to dodge recruitment pitches from some very persistent people. On top of that, Yui must figure out how to respond to a sudden confession—one she can't bring herself to refuse. Her one consolation is that the camp is in Bahal, a town famous for its sweets, so she'll at least be able to eat as much as she wants...right?! This summer, anything could happen, and everyone—even Yui—is keeping secrets.
