FutoKoko

KokoFuto is a hey shipping from the fandom Darling in the FRANXX.

Fanon
Kokoro and Futoshi have known each other since they were small children living in the Garden but they had very little interactions with each other. When they are 14, they are assigned to the same FRANXX squad and, after passing their capacity test, they are paired up together. They quickly became good friends and developed a strong friendship.

Fandom
This shipping started off descent with the fans, as many found Futoshi’s crush on Kokoro to be cute and sweet. However, it diminished as soon as Kokoro paired with Mitsuru during the partner shuffle.

Reactions to the partner shuffle have been mixed. Some were angry that Kokoro broke Futoshi’s heart and ended their partnership in favor of being near the boy she liked (Mitsuru) despite how good Futoshi treated her and the fact that she promised to be his partner forever. Others had no problem with it because Kokoro does admit she didn’t feel the same way as Futoshi felt for her and she felt bad for hurting him, and continued her friendship with him to avoid a rift with him.
