Canon
While the two are not shown interacting much, Kokichi called Rantarou his "beloved Amami-chan" and cried when he saw his corpse. However, his attitude changed very quickly, making it hard to tell which one of his reactions was truthful. Kokichi states how he doesn't care about Rantarou and claims to Shuichi that he doesn't actually want him to come back alive, though, this could be a possibility as one of his lies.

Much later, it's seen that Kokichi has the life-like statue of Rantarou made by Angie hanging upside down next to his bed. This implies that Kokichi misses him and hints that his reaction to Rantarou's death wasn't part of his lying nature.
