Exactly, and they are very caring for each other, they don't said it, but in the small action we can see it. They aren't the type to say "I love you" but they will let the other part know, more like action then word's guys. And when Jay say that Yohan can use him and ask if he wants all his money and possession is a way to say "I love you" bc he wants give everything in him to Yohan and Yohan knowing that and don't do it and didn't strip all the things from Jay is also a way to say "love you too" bc he doesn't want to prejudiced or do bad to Jay and he gets worried/mad when see Jay losing to the old man. Those actions and much more shows how they respect and care for each other.
Clearly they aren’t like normal couples they have a mutual understanding of how they feel about each other. And plus never once did they say they loved each other . Just because they don’t say it doesn’t mean they don’t care about each other .
