there's one particular mischaracterization of diluc that genuinely infuriates me and that's when people say he doesn't know love.
all he has ever known is love. how to love, how to give it, how to feel it.
the issue lies in the fact that he didn't know when to stop. even if he understands now, he still can't do it because he doesn't know how to.
i think his heart didn't know how to compartmentalize. he gave the whole of it away to everyone he loved because of it.
he saved everyone and everything he had ever loved in one space. as a kid, his heart probably thought that everyone was getting a bigger space, not about how messy it had gotten.
and, honestly, i still think he struggles to give only what is needed. he just has a better poker face now to hide it.
everything he has ever felt — not just love — is in abundance. he just didn't have a big enough container to hold that big of an amount of one thing, let alone everything.
love is something he can't draw a boundary for.
that's why his actions — his reactions — make so much sense to me. i'm not saying that he's right in what he did, neither am i making any excuses, but his actions are so in line with what i understood his character to be that they feel so natural. so him.
diluc's problem isn't that he can't love, no. the problem is that he loves way too much. so much that he can't help but let it dictate — or at least influence — every other emotion that he feels.
i think his name backs it up perfectly, too. no one in the world has the power to stop the daybreak; it spills over to bask everything in its way in light and warmth regardless of whether they are needed or not — not even itself.
