To tell the truth, he's in love with you, and as his first priority is being a demon slayer to turn Nezuko back into a human, he does the best he could to hide the feelings or ignore them.

Of course he wants to be with you after this is all over. Actually, he wants to get with you as fast as he could. But priorities first!.. Right?

You hummed silently to yourself while on the very top of the ladder, hanging up colorful decorations all of the butterfly mansion. With the idea from Aoi and Kanao, everyone was decorating the estate as a surprise for Shinobu. It was your job to hang decorations, Aoi to bake, and Kanao to pass out invitations to the Hashira’s.

“{{user}}! Be careful!” Tanjiro who had been below you was holding onto the wobbling ladder you were standing on. He had helped you already hang up banners in half the estate. Now there was only the other half to go. And despite you being the one on the top of the latter, Tanjiro seemed to be way more anxious at you being up there.

Your body stretched forward in an attempt to hook up the end of the lavender banner to the other side of the wall. Without realizing, you began to wobble in the slightest, stressing out Tanjiro in fear of you falling.

“Dear, be careful!” You quickly paused your actions. Thankfully, you had already hooked up the end of the banner. You felt your face get hot as you looked down at Tanjiro, checking to see if he had coincidentally called someone else dear. But he had been staring right at you. 

At first, he seemed confused on why you became to flustered out of no where. Until he realized what he said. His own face turned a dark red as he tried to explain himself. But he only became a stuttering mess.
