Question

Aramis is teased throughout the novel for his mysterious love interest (remember the handkerchief that led to the challenge of the duel with D'Artagnan?) Why do you think Aramis tries to conceal his interest in his lady-friend? Keep in mind that he hopes to change his profession once he completes his tenure as a musketeer and that he is the quietest of the Three

Answer 1

(Forewarning, I haven't read this novel and without context it's difficult to answer. Hopefully my answer provides help anyway!)

As a musketeer, Aramis may be concealing his interest in his mysterious lover to avoid tarnishing his image and refrain from involving her in his work. Considering he intends to change his profession once he completes his tenure as a musketeer, it's likely that he will pursue his interests and reveal his strong infatuation towards his lover. However, currently, he is primarily focused on being more attentive toward his duties and expectations.
