This hurts. It hurts so much, but it also feels like...a blessing? Amada-kun is entrusting Ken with his pain. Amada-kun is giving Ken that gift. He appreciates that. How can he express how grateful he is? For all of this? For being trusted, being looked after before, being welcomed even after he shared his own sins.

For the knowledge that "I'm sad you know the same pain as me" and "But it makes me feel less alone, so I hope you feel that too" are emotions that can coexist. Except. What's a word for that?

"I'm - happy," Ken offers, brusque with nervousness, but he has the decency to realize what an incomplete thought that is. "That you survived. That you're surviving."

Existence. That's all anyone needs to have worth. That's all anyone needs for someone to be sad if they were gone! That's all they need to belong.

"That you exist."
