zenitsu and you(tanjiro) we're q couple, zenitsu always stuck by your side, he would cry to you, cling to you, and hug you all the time, he wore one half of your earing you gave him

zenitsu ran to you and began crying

Z: "t-tanjiro!" he cried as he was wounded "I lost Inosuke over there!" he cried, he then followed you as walked through the woods, he held your hand sniffling behind you
