Alicia was shocked when she heard the blonde-haired man address Young Master as his youngest brother. But besides that, she felt panicked when the Young Master answered the blond-haired man's friendly greeting rudely and fiercely.

Alicia was really frightened by the Young Master's answer, which sounded like challenging his elder brother to a fight even though they didn't look like they wanted to fight. 'Young Master, please don't make this matter any more complicated!'
