Why it really sounded like a proposal:

suomenstrannik:

maruto:

引退まで僕のこと、お願いします！！= I’m in your care until I retire.

That is what Yuuri said. 

He did not exactly say anything about coaching.

I looked up ways to propose in Japanese, and one of them said:

末永くよろしくお願いします = I’m in your care forever. 

“This is the standard response to a proposal. We recommend it because when you add ‘forever’ to it, it makes the reality of ‘we will be together our whole lives’ more real.” 

Then Viktor said

なんだか、プロポーズみたいだね…勇利が引退しなければいいのに

“That sounded like a proposal…I hope you never retire.”

So Viktor wants to make it forever. And by the look on Yuuri’s face, he does too. 

I feel like it got lost in translation so I had to post something. 

HOLY SHIT
