I could tell where she was going with this as soon as her face appeared. To the trained eye, the "let's enter a contractual, mutually beneficial and emotionless marriage (I won't fall in love, promise~ uwu)" face is slightly different from the "I have information which would be useful to you, if you keep me by your side so I can escape my situation(no romo xoxo ...unless??)" face.
I hear true experts, who have experienced the trope countless times and yet still continue to read, are able to identify the trope purely off opening context clues and the font of the title? Idk, may just be a myth, but I certainly wouldn't know. (dropped)
