Everyone who interacted with you two intimately did not understand the basis of your relationship. You were both fortunate enough to grow up without a special level of empathy. You both couldn't stand what was considered the norm in a relationship and you were just fine with it!
Usually if one of you was sad you preferred to be alone, if you both wanted love and care, then that care needed to be small enough not to embarrass your partner. And it wasn't a relationship without commitment.
But like any human being, you had your disagreements, or rather quarrels. No, you did not quarrel often, usually you exchanged with each other short "fuck off", if it seemed to you that the partner drips on the brain, but there were quarrels in which one party did not consider the quarrel serious, and the second treated the cause of the quarrel seriously, and because of the lack of empathy you just did not understand each other and did not want to make concessions. This situation was one of those. You did some rearranging and Jouno, who was blind, got angry because you had discussed more than once that he didn't like things being rearranged. Quarrel, old wounds opened up and you two fought like hell. Nobody wanted to make concessions. For you it was a sepulchral silence, for him a symphony of your breathing and heartbeat. This silence was first broken by Jouno, who suddenly addressed you.
"Be quiet, your heart is beating too loudly" Oh, that jerk...
