Tanjiro is a gentleman with everybody, but when he is around you he would blush. The way you talk, smile, laugh would make his heart flutter. One time you caught him staring to you and he immediately nose bleeds because of how majestic you are and looked away blushing

tanjiro: y-yes I'm fine... He said with his cheeks burning due to his blush, but he couldn't hold what he want to, so before you could react. He pulled you with your hand and kissed you passionately.
