hmm but remember when Ryuzaki said 'why did you let yourself get shot so easily' (i think?), although you're right on the fact that he wasn't surprised and when he said he was part of the plan Hirata had put together... AAAAAAAARRRRRRRGH!!!! please... some... one... trans... late... thi... s....
Okay so this is what I think-
Remember Yashiro told Ryuuzaki he should change his illegal business location cuz the police is up on him?
Ryuuzaki is handling illegal trafficking with foreigners (probably Chines) along with Hirata. I can only guess that Ryuuzaki told Hirata Yeshiro has connections in the police and he suggested that they will change locations.
Hirata got freaked out and told the Chines that Yashiro may leak out to the cops. The Chines sent a hitman, Hirata probably knew it's going to be Yashiro and told Ryuuzaki they are sending the hitman to some rat who told about them to the police.
Ryuuzaki found out it was Yashiro they were going after in the first place. Hirata probably doesn't know the relationship Ryuuzaki and Yashiro have (even though they are something like rivals they still know each other from long ago, they won't just go randomly and kill each other.) so he just told Nana that it was Ryuuzaki. Of course later on when Yashiro finds out this is what Nana is thinking he is stopping him cuz he knows theres no way Ryuuzaki would try to kill him.
And the rest I really don't know it's all just guessing around with blindfolds.
It was said in ch. 13 summary that it was Ryuuzaki that sent a hitman, but ordered not to chase Yashiro and not to hurt/wound him fatally. I think Hirata was a schemer behind it.
I'm happy that some people think the same. I'm sure that Hirata is the big boss in this story. Ryuuzaki doesn't strike me as the vilain type here.
Anyways I can't wait to read the next chapter.
SPOILER/ PLEASE DON'T READ IF U HAVEN'T SEEN CH13
So I've read a summary of chapter 13. Maybe I've misunderstood something since I'm not a native english speaker, and I don't understand chinese or japanese. But here is what I think happened:
So yes, Ryuuzaki was the one who sent the hitman to Yashiro. But, Hirata was the one making him do it. I think Hirata tried to make a deal with him to eliminate Yashiro because of the leadership thingy. He thought it would be okay since Ryuuzaki seemed to hate Yashiro with passion.
BUT, that's where things got wrong. Actually, Ryuuzaki liked Yashiro since a long time (If you pay attention to the flashbacks, you'll see a hint of it). And instead of telling the hitman to shoot Yashiro in the head, he told him to just fire and injure him badly enough to be at the hospital for a long time (so he would away of other dangers). You've to agree with me, it's reaaally weird that a pro hitman missed a defensless target, just in front of him, 3 times!! Anyways, that's what the hitman fessed up at Hirata's men. And now they want him to pay.
So to sum it up, RYUUZAKI TRIED TO SAVE YASHIRO'S LIFE. At least that's what I think. Are you thinking like me?
