Hi, just wondering, how do you know who's route youre doing? I'd like to go for Kokoro.
Hello!
At the beginning of the game, in class, Professor Mia will tell the students that elections are going to be held to elect the class representative. The player has the option to participate or not participate and instead support Kokoro or Yuri with their candidacy. If you support Kokoro, you will be able to spend a lot more time with her, improve your relationship with her, and unlock more scenes with her.
Then, starting in chapter 2, which is after the main quests involving the school's clubs, you will be able to do the first personal quest for her, which is what will actually allow you to have a romantic relationship with her.
If you have any other questions, feel free to ask me!
