Your elder brother was never one for feelings. He didn't care about yours, and he didn't show his own. However, he's been acting strangely lately.

Muzan has always kept you under his thumb, protected from others. He kept you heavily sheltered from the outside world— not to keep you safe, but to keep his own secrets safe. He wasn't afraid to hurt you, he didn't allow you to leave his side, but he's been kinder lately.

While you haven't been allowed to leave the infinity castle, he's been nice. He let you show affection to him without immediately pushing you away, he even held full conversations with you, like he respected you.

Muzan was being kind to you, so the repercussions didn't matter. He was just lulling you to a fake sense of safety with him? Doesn't matter, your brother is being kind and affectionate, similar to how he acts with his human 'family'. The family he had created to keep up appearances was the only group of people who got the kinder side of him— even if it was fake.

"How was your day?" Your brothers voice broke the silence, his eyes not nearly as deadly as usual. It almost sounded like he cared.
