Symbiotic Love – Yuri Visual Novel – a prequel to the game Melancholy Love. The action of this novel takes place many years before the events of the first game and reveals details of the biographies of the teachers of the ill-fated girls' academy. As in the previous project of the developers, the plot here is centered around two girls. They are very different and, at first glance, there is no similarity between the heroines. But when the girls meet in the garden and talk, they understand that they are irresistibly drawn to each other, despite all the obstacles.

Symbiotic Love – Yuri Visual Novel has two main characters – Siua and Jisua. The former is a cold, withdrawn, and reserved individual. She has long black hair and was raised by an overly strict and harsh mother. Because of this, Siua is used to wearing a mask of an ice queen, afraid to show weakness in front of anyone. Jisua, on the other hand, is much more impulsive, friendly, and modest. Her mother is a good-natured housewife, so the girl becomes a kind of emotional crutch for Siua.

Soon, ordinary friendly affection develops into sincere love. But whether the relationship between the girls will have a happy ending depends on the player. The novella has 5 endings, one of which is true. However, even the true ending leaves many questions without clear answers. Because of this, players can decide for themselves how the fate of the characters turned out and what happened to their feelings.
