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 seated next to her, Alweiss Rockmann...!

Volume 1 of the I Want to Be a Receptionist in This Magical World manga series by Jan Cash.
