Remus nor Mia can engage in dating activities with anyone else while they're together. It

"Says who?" Lily asked.
"Society," Alice answered. "They could break it off again and get back together a
year from now—again—but everyone here in the Great Hall saw that letter. Some of the
purebloods would consider Remus to not be a man of his word, and Mia, well... they
would not have good things to say. Depending on connections, it could derail their future
career plans or marriage prospects if they treated the Letter of Intent frivolously."
Mary nodded, grinning as she read the letter before placing it back in the envelope
and handing it to Alice. "Mia could have actually taken this letter and burned it, and Remus
could never ask for her hand again if she denied him."
"Why do you think you've never gotten one from Jamie?" Mia asked Lily with a
chuckle. "He knows you'd shred the thing, and then he'd never have another chance with
you."
Lily scoffed. "He doesn't have a chance with me regardless."
Mia smirked as she saw the curiosity flash behind Lily's eyes. Ever since that
Amortentia class, Lily had realised exactly what, or who, she was smelling behind the
signature potion. If James did send her a Letter of Intent, Mia wondered what Lily's
reaction would be.
