I Want to Be a Receptionist in This Magical World, Vol. 1 (manga)

Ever since she was little, Nunnally has always wanted to be one of the graceful, capable receptionists of the Hall. As only first-rate mages are hired for the position, she enrolls in the kingdom’s magic academy to hone her skills, where she feels out of place in a classroom of nobles—including a genuine prince. She decides that despite being a commoner, she’s going to be the top of her class...but for some reason, she just can’t beat the one person she’d most like to—the snobbish boy seate...
