For once the wording actually completely makes sense. She has that terrible habit of being unintentionally lewd and he wants to tell her his feelings without "using" their temporary relationship to satisfy his love. Just really bad timing.
Usually misunderstandings have really dumb wording but...
He/she is constantly mixed up when mentioning Young lady Lucio. Was very confusing at first, especially since they basically turned her into a guy visually. Thought it was her brother, or that she's a guy, or that it's someone else or something lol.
