It has come to my attention that people in the fandom don't understand the use of implication, so I will now break down easily as possible for people that don't believe Cordelia sexually groomed Laito. @dl-drama-cd (Tws for rape and incest)
The conversation atop is one shared between Laito and Cordelia. Take note of the background. It is a bedroom. Not the garden or the kitchen or somewhere aesthetic in the moonlight, it is a bedroom.
A bedroom is used for sleeping or as Reiji likes to call it, private activities. We all know that people who usually share a bed are relatively close in terms of relationship, it doesn't matter what kind, they just need to be close.
Cordelia shares no emotional/maternal bonds with her sons. She is often described as crass or cold. Why are her and Laito in a bedroom together if they do not share such a bond?
A bed in media is often used (with context) as a symbolism for lovers sleeping together, because that's exactly where it happens.
How do we know that something more sinister is going on than just a mother and son talking? We can figure this out based on the conversation.
Let's look at what's said between the two.
In the first image, Laito poses a question to Cordi. He asks her, without explicitly saying what "it" is, what's her reason for doing this?
This is a canon interaction between these two characters, where character 1 (Laito), is unaware of the intentions that character 2 (Cordelia) possess. Which is why he is asking her, why she is doing "this", because he does not know why this is happening to him.
Cordelia then explains, also again without directly saying anything, that she does "this" because she loves him. This is Cordelia's reasoning and answer to Laito's previous question.
That's pretty straightforward, I don't think we need a paragraph long analysis on that.
Laito, who then repeats the word, love, in a questioning manner.
Why does he do this instead of just accepting her answer as is?
Because he is simply not satisfied with such an answer. Why isn't he just accepting her word as is? We, don't yet know because once again, the context in this current conversation is not said.
Continuing, we see Cordi backing up her previous statement by saying that there is no world out there where a mother doesn't love a son, and if there is, what kind of world would it be?
She tries to explain that Laito shouldn't question her actions, but rather accept them as they are, because that's an inherent profession of love between mother and son.
Laito, in response, flatly says that a world without love between mother and child, is the one that they live in.
In other words, Laito does not accept that "this" is what paternal love truly is. He believes that his mother does NOT love him, which we can easily pair up with his earlier question "Love?".
Now that we have some form of context to the character's inner thought process and what they are currently feeling, we can put together some pieces on what kind of conversation is actually going on.
At a first glance it can be assumed that a son is doubting his mother's love for him, because well, that's exactly what's happening.
But if we speculate a bit more on the background, and the given context of the conversation, we can now say that the truth of the situation lies within the more subtle clues.
This memory, isn't a pleasant one. This conversation has already happened and Laito is simply remembering it. You can use the images provided to reverse google search the complete scene for further proof, but as already stated, this is NOT a conversation he is very fond of.
The conversation that these two are having, shows us that one person is satisfied while the other isn't for whatever reason that may be. I've broken it down already so you can understand it a bit more, but feel free to once again do your own research.
The implication of the background. Like I've previously stated, I broke it down at the start of this post. But let me be absolutely clear and reiterate this, THE REASON THE BACKGROUND IMAGE IS HAPPENING INSIDE A BEDROOM AND NOT ANYWHERE ELSE (even though you can suck someone's blood anywhere you wanted to) IS BECAUSE THE CONTEXT LIES WITHIN THE BEDROOM ALONE. The creators didn't just randomly choose a free png of a bedroom for a conversation where a child asks a parent why they're doing something, that the child feels like diminishes the sole intent of paternal love. Context clues, matter.
Now then, I'll go on to add another image where I'll make a very short and factual analysis without hypotheticals or opinions being used.
Laito in this scene, is completely naked. He is naked and with a solemn expression on his face, thinking about his mother pleasuring him. He is also reminiscent on the words his mother has told him, that being "I love you, Laito".
Cordelia then says that "That kind of thing is just something given in exchange" when the words I love you, are said. Laito, once again, admits that he was being pleasured while thinking of his mother. [End analysis]
We can speculate that since he is thinking of his mother and pleasure at the same time, she is the one who is giving it to him.
Why do I think this? Because he is completely naked, his only thoughts being his mother's voice. That being said, we can now say that what is being "given in exchange" in Cordelia's words, after saying I love you (or perhaps vice versa, where I love you comes first) is pleasure.
I have a couple of links here we can make with these couple of images alone.
In the first part, we see them talking in a bedroom and the conversation eventually leads to satisfaction, in terms of "once I am satisfied with the outcome, there should be no question". She also references love here, as she does in the latest image I have provided.
With the context that we have now we can equate love to pleasure. And Cordelia states that she loves Laito multiple times throughout just these two scenarios.
Now, my interpretation of this is that Cordelia is clearly raping her son and using "love" as a means to mask, and more so, normalize what is happening between them. (I say normalize because Cordelia tries convincing Laito that this is what goes on between mother and son in the first conversation).
However, even if you do not share the same perspective, it is still abundantly clear that Cordelia Sakamaki, first wife of Karlheinz, daughter of King Burai of the Vibora clan, mother of Ayato Sakamaki, Kanato Sakamaki and Laito Sakamaki, is giving sexual pleasure to her son. Whether it is by bloodsucking, or by sex, or both.
She is sexually grooming Laito by giving him these sensations a mother should not be giving her child, and is committing an act of incest.
