A second chance after they hurt him and their other mist

Tsuna is betrayed by all of his guardians except for one of his mist guardian. His mist helps out in anyway he could, but he knew he could not fill in the void. The pain of his sky could not heal unless his other guardians except him after he killed to protect them.

Why couldn't they see he killed that person to protect the other's? Why he the mist could only see it? He is gonna make the others regret what they are doing to his sky. He did all that he could to lessen the pain, he even did most of the paper work that his sky didn't noticed. He even had to force him to sleep, even though he couldn't sleep. The only way to get tsuna to sleep now a days is to stay with him until they both fell asleep.

Now however an assassin comes to kill his sky but he takes tsuna's place without anyone knowing. He uses his mist to look like his sky while his sky looks like him.

He knew he would die before allowing anyone else to hurt tsuna. Although he knew that he might die today, at least he knew tsuna, his sky will not be dead.

Despite knowing this, he couldn't help but feel abit sad, he was gonna break their promise. The other guardians show up to stop their sky from being killed, it was kinda already too late since he was shot in front of them.

Only to find out that it was mukuro using his mist to protect their sky. The mist was dying, they knew that. But he was saying his last words when primo shows up.

He gives them a chance to change everything and not allow their other mist to die and finally expect their sky. If they didn't take it their rings will reject them and tsuna might just begin to hate his guardians. He only had mukuro and now has no one.
