Nidome no Hatsukoi ga Kojireta Majo wa, Tokimeku to Houden shimasu

"Diana isn't cute!" Those words from Julius, her first love, traumatized Diana and turned her into a shut-in who stayed at her noble parents' manor out in the countryside. She became an artisan known as the Witch of Roemer, spending her days making the magic tools she was excellent at creating. One day, Diana returned to the capital city to attend a ball and ran into Julius again. As she tried to forget her fleeting feelings of love for him, her overprotective brother created a "Man Repellent Ring" that would drive back any annoying bugs (men) who got near Diana... But it started shocking Julius!
