Headcannon: Sakura pulls all-nighters because of her work and Sasuke does it with her so she won't be lonely but he says it's because he'd tap her and keep her awake

Sasuke at 8:00 PM: everyone on this earth except Sakura and Sarada could die and I couldn't care less

Sasuke at 10:00 PM: lol I was such a whiny genin

Sasuke at 12:00 AM: Death is imminent, we're all literally just sacks of rotting flesh

Sasuke at 2:00 AM: Knees are just leg elbows??????

Sasuke at 4:00 AM: Everybody hates me deep down they're just really good at convincing themselves that they don't-

Sasuke at 5:00 AM: *violently sobbing* and then Sarada called me annoying

Sasuke at 8:00 AM: a plague could literally wipe out everyone in this village except Sakura and Sarada and I wouldn't even care a little bit
