Starry Night

At the end of Episode 12, why didn't Can buy Sanem's explanation that she isn't attracted to him? Why didn't he go away like all the other previous times? Why was he still fighting for her? Of course, when he kissed her at the opera house she mentioned about her heart getting jumbled, so he knew about how she was truly feeling. But what if there's more to the story? Here might be another reason why Can didn't want to run away from Sanem just yet, and why he wouldn't accept her 'I like you as friend' explanation.
