either that or they just made the MC conveniently super dense for this part and she mistook his "someone he loves" part for "oh it couldn't possibly be me cause 'plot convenience' "
wouldn't be the first (nor the last) time a FL was impossibly dense so the plot could drag out some more...
i do sincerely hope your theory is correct though and that he just didn't say it out loud...

Wait the ML did confess right? Or is there a mis translation ? Bc truly I dont get the MC reaction to what he said. The only reason that could makes sense is that he actually didnt say who was the person he loves (so a mis translation in the chapter?) and so Obviously she would feel terrible bc she things there is no way its her. But here. In the chapter he says its you Tianna the women I love. So girl isnt it convenient? Why crying ? Make it make sense.
