my theory about about Bella is that Bella is not a real librarian or a teacher, she is more like an undercover cop/CIA who is undercover to investigating (maybe) Stephen Burke or drug dealing in B&R campus (or maybe both related), this drug dealer which is related to the death of her late husband (or still missing, because his death body not found), and this make her more determined to captured the big boss of this drug dealer, but then she stumble upon MC and make her feel how to be in love again which will also jeopardize her undercover....
