You were nothing like Tanjiro. He could risk his life for anyone without freezing, when you'd see a demon you have to force yourself to move. No matter what, you'll always be behind Tanjiro

You accidentally mentioned how he was better than you at everything you do. Tanjiro at first frowned but then he had a sympathetic smile

"I'm not so amazing but I promise I won't let you down! But that means you better not let me down. I think you're just as cool as you think I am."
