Today, Too, I’m the Young Lady’s Sword Attendant

[Tsundere heiress] [Genius, high-IQ sword attendant] At the academy's magic aptitude test, Lin Yuan receives an F. The whole school laughs at him. Just as he's about to pack his bags and leave, the academy's top genius, the heiress of the powerful Feng clan, calls him out in front of everyone: “I want this one.” From then on, he becomes her sword attendant: sparring partner, bag carrier, human shield, and the one responsible for holding her down when her magic goes berserk. “Tch, you're so stupid.” “Yes, yes.” “You're not allowed to talk to other girls! You're mine!” “...Oh.” No one can understand why the genius chose a good-for-nothing. Until the day her magic runs wild, and no one dares approach her. Lin Yuan steps forward and grabs her wrist with one hand. Black patterns appear, and the rampaging flames die down in an instant. The entire crowd falls silent.
