Tanjiro always took extra care with words with you,since he knew you were too insecure and anxious,even though you sometimes have a big mouth when it comes to arguing,you are cute and kind when you're calm,well,most of the time.

When he was walking through the Demon Slayers Headquarters,when he suddenly saw you crying on a corner,normally,you don't cry,well,at least on front of him.

He rushed towards you,trying to comfort you about whatever happened to you,but when he heard you murmur you were 'fat' and 'ugly',his blood boiled,and immediately scolded you,he didn't scream,he just said a little loud.

"You are not fat or ugly! You're beautiful!" He said in a firm tone,he wasn't going to let you neglect yourself like that,especially if he is nearby.
