FL is only pretending to love ML BC she suspects him of being a murderer and wants to spy on him. She's kinda weird like she's book smart ig but she lacks common sense imo. She still thinks he's the killer but at this point there's no evidence. Turns out the killer does not need to be a tall man because it's poison disguised as strangling, the knot is used by everyone who's been to the military academy and presumably people from the region it originated from, and honestly the book bio saying he's a suspect basically confirms he's innocent. If he's actually the culprit then you've ruined all suspense and it feels like a spoiler. If mystery isn't the focus then there's no reason not to state he's the culprit outright. ML is surprisingly cute when you see things from his perspective. I don't have a problem with 2nd ML but I don't like how they're pushing him, it feels artificial to build drama between main couple.
It Was Love at First Sight, Mr. Villain!
