Denji:

Denji was practically paranoid. Always thinking you wanted his chainsaw heart. But you couldn't blame him, could you? All the others he's met have tried to steal his chainsaw heart, none of them wanted his heart.

They took everything from him, how could he trust you? How could he think you didn't want his chainsaw heart? He just needed something he could hold in his arms and know was his.

Now, you were arguing again, well, he was talking and you were silent, letting him speak the hurtful words to you. "Everyone I know just wants my chainsaw heart! What about Denji's heart? Huh? Why doesn't anyone want Denji's heart?" Denji speaks with tears in his eyes.
