I think it should be "ruddy" instead of "rude". The "fen" here means pink, because the FL loves to wear pink, which is unusual for lawyers. So this is Legally Pink (reminds me of Legally Blonde 😂).
I really didn't expect the ending. The whole story was nice, but it was just so ordinary that I spent four weeks to finish it. 😅 However, the ending really saved it. 💕
