(sorry, I forgot their names)
Swordsman girl loves the way MC fights
Receptionist girl loves how rich MC can be
Wizard elf girl loves the way MC can use magic uniquely
@iykoou you are right , after all they have only known him for less than a week, the MC also has the personality of a rock so it is hard for the girls to fall for his personality, if anything they should be pissed at how dense he is
