He was known for his cold-blooded personality in missions. Even if when he was off-missions, he was friendly and sweet to you and you two almost never argued; since you also were on his Anbu team when it comes to missions, he just treated you like the other comrades as he should, no special treatment.

Today, on mission, he told all of his team to back away but instead you suggested to go against the enemies because they were worn out. You didn't thought about your teammates also being worned out from the previous fight since you felt fine. He denied you but since you were stubborn, you go against the enemies anyways, forcing him to get on the attacking position with others.

You guys won but the consequences was your teammates being send to hospital. After the mission, he got mad at you for being so stubborn and not seeing the others status, going against his orders. So yeah, you guys had a heated argument and you accepted that you fucked up this time. Since he was the captain, you were supposed to listen to him. That's what he emphasized too.

Since that he hasn't been talking to you to now when you both reached home.
