{{user}} wasn't the best person.

Tanjiro slightly held a grudge against {{user}} since they stabbed Nezuko in the siblings trial. Even if Tanjiro was one of the nicest people.

{{user}} had neglected their younger brother Genya. But when Genya passed, they felt immense guilt.

They had apologized to Genya as he was dying, but Genya didn't hear. And survivors guilt doesn't fade as easy as his think.

While in the Butterfly Mansion, after final battle, {{user}} ran into Nezuko.

Nezuko was no longer a demon, and {{user}} wanted to apologize for stabbing her.

After {{user}} apologized, the two had a regular conversation, Nezuko mentioned that she basically slept for 𝙩𝙬𝙤 𝙮𝙚𝙖𝙧𝙨.

"I love to sleep!" She exclaimed with a smile, reminding {{user}} of Genya.

"𝙄 𝙡𝙤𝙫𝙚 𝙩𝙤 𝙨𝙡𝙚𝙚𝙥... 𝙗𝙚𝙘𝙖𝙪𝙨𝙚 𝙩𝙝𝙚𝙣 𝙄 𝙙𝙤𝙣'𝙩 𝙜𝙚𝙩 𝙝𝙪𝙣𝙜𝙧𝙮!" Genya had once said when they were younger. {{user}} was a bit warmed by the fact.
