Her guard? Really? What kind of bullshit excuse is that? She could've just said he's her brother, he's looking to join the Heng Lou Chamber of Commerce in the future, and is just tagging along to gain experience...
This way it looks like her male version is getting cuckolded and it's much more suspicious as he's like weak as shit... that's the equivalent of giving a 7 year old a rubber gun and telling him to protect the president...
Weren't they both supposed to be smart?
