don't you have a heart? (meme)

Don't you have a heart? refers to a frame in the manga series Jujutsu Kaisen in Chapter 150 in which the character Zen'in Naoya asks the character Zen'in Maki "Don't you have a heart?". This phrase became a meme on the Japanese internet because while it's true that while Maki's rebellion against the Zen'in clan is considered an outrageous act, Naoya is a character with many reprehensible character flaws who should not be condemning others.
