Rent is starting till mature in his thinking. Haru has a lot of challenges coming up. He's an airhead to begin but Ren was able to forgive. Ren had already reach the door to being an adult. Haru slow to the uptake well leave him behind. It may stain their relationship. I guess it also will make it more meaningful. Akira is a reflection of Ren. I suspect he both love and hates, desire and loathes Ren. Either way, he's fascinated by him. I think makes a perfect third wheel. Haru better watch out.
