Guh, Match is basically admitting the he's in love with both of them but doesn't know what to do about it. He loves Mix and he loves Ryu and he just wants them both in his life but he doesn't have a solution for that.
And Ryu doesn't have a solution either. He loves them both as well, he cares for both of them so much, though his feelings for Match are obviously stronger at the moment. He's trying so hard to convince Mix to stay and to try and I don't even think he realizes how much he cares about him.
Mix might not realize how strong his feelings towards Ryu are, but his love of Match has finally just driven him beyond that. He can't handle the idea of one rejection, let alone two, so he just keeps it all to himself and hides behind removing himself from the narrative rather than staying in and risking himself.
Honestly, the three of them make such a good group and it's so painful to watch them almost get there and then just not quite make it every single time. They all care about each other so, so much but Match isn't straightfoward enough and Mix isn't ready to listen and Ryu is trying so hard to do both.
