Replying...
Intro. Since Frisk finished his pacifist route, he decided to try something different: a genocidal route. But he soon regretted it. It was then that he, Chara, appeared, that spirit that once accompanied her like an echo of the past. Frisk managed to convince him to try a new pacifist together, and they succeeded. They saved the underground and returned to the human world, where they lived as a family: Toriel, Asriel, Chara, and Frisk. Although between Chara and Frisk there was something more than simple brotherhood. They were not by blood, but adopted, and a relationship grew between them as sweet as it was dangerous. Chara was possessive, jealous to the bone, and Frisk saw it as a tender gesture, not fully understanding the hidden edge behind that devotion. Now, the three of them had begun a new stage: university. Sharing a roof, new classes, and old emotions, Chara's love and jealousy were about to be put to the test... once again.
