Ch.1
We don't know he did for sure. We know he raises his knife and it looks fromt hat angle as if it is going to his neck. We see a tattoo, and it could be falling, and there appears to be large zig zag near the back next to the family mark, and some smaller zig zags. I admit that the cutting the tattoo theory seems likely, but we don't know exactly what happened yet.
Just for fun, my current speculation (which could be all off) is that Logan will tell Kyon that letting Lucaon drink life force will turn Lucaon into a zero slowly or otherwise be bad for Lucaon. Or Logan will tell Kyon some other lie that makes Kyon think he has to cut the tattoo off instead of facing Lucaon and asking to leave. Kyon runs out in the snow all dramatic like, and cuts off the tattoo, but also cuts his own neck or somehow injures himself. Lucaon feels the break in the connection and runs out after Kyon. Finding Kyon bleeding, Lucaon panics and heals him, draining his own strength and making him need to temporarily walk with a cane. Lucaon puts the tattoo back on Kyon to heal him better and to feed his strength to Kyon. But once Kyon is well, Lucaon is pissed, and at first cold. Lucaon starts treating Kyon like any other servant, until chapter 0 (after which Lucaon may decide Kyon should not leave his bed, ever).
Maybe in ss2 Lucaon will misunderstand that Kyon betrays him and expel Kyon. And when he meets the enemy and has to fight, Kyon suddenly appears and gets wounded because he tries to protect Lucaon when there's an enemy behind him. Lucaon kills all the bad guys, realizes that he misunderstood Kyon, Kyon is nearly dead so Lucaon give him his strengh though it may kill him. Luckily Kyon is saved, becoming a royal blood and the 2 of them lives happily forever. ╮( ̄▽ ̄)╭ Just for fun! (And plz don't mind my bad English)
i like your theory. it has potential. something will happen to break or almost shake their commitment. it will either make lucion more aggressive or receptive towards kyon. the way lucion is it will take a lot for him to admit he loves him. he has trust issues.
It might happen when lucaon finds the pictures and the knife in kyon's room. Just my thought.
But Lucaon gave him the knife in the first place :D why would he be mad about something he gave? Pictures might piss him off for sure!
Because he didn't return it. :P
the pics will anger him and if kyon uses the knife to break the seal than lucaon might tie him up. hell, why are they on hiatus???
Well it's not so easy to draw a webtoon.It creates a lot of pressure on the authors.Anyway they said they'll be back after 2 months . I hope they will be back on march. I saw in the special chapter they may return on march 2. I used google translator to read that so im not sure abt the date.
Anyone interested to think of the reason which will lead Kyon to cut his tattoo? (=・ω・=)
Hmmm let me see I think maybe Sihan will tell Kyon that from the main reasons that Lucaon wasn't able to help his family was because he was helping him and maybe Kyon has discovered Lucaon treat him violently is because he actually knew he's the same child he saved that day and above all that he's a servant.... Maybe...
I know it sound stupid but I'm just trying to guess the rest of the story ┗( T﹏T )┛
