Sirius Black

Sirius was walking with James, discussing Regulus, when suddenly a familiar figure appeared at the end of the corridor, it was Regulus's figure, James did not recognize him and gasped, muttering that the guy was handsome, and Sirius raised an eyebrow and slapped James on the back of the head, and then when Regulus got closer, Sirius rolled his eyes, and James simply remained silent, but his ears turned red treacherously

Regulus had very curly hair that day and a very handsome appearance and pleasant aroma.
