I hate to be the one to say it, but a lot of the time, what the MC does just doesn't make any sense. Like, not telling Ikuya and Lioji about the suspicious man she saw in the cave, or going to an abandoned house in the middle of the night, or wanting to after the murderer for no real reason. Also, I feel like her personality is not consistent sometimes. I know this is a free game and am glad to be able to play it, but I thought I should throw some constructive criticism your way.
she doesnt tell them about the man as she wants to investigate him herself, she said she is a curious type, and telling her friends about it would cause alarm and they would tell her to stay away and Lioji would probably tell his dad
