Thank you, I'm glad you like the game setting and plot development so far! Sooo hehe technically there are two yanderes, but they're very different in how they express that element of their personality. One of them is a hidden/secret route that doesn't become available till later in the game and is not listed on the game page under love interests. I don't want to give too much away by telling you the other, but chapter two will be releasing verrrry soon, and there are a couple major hints about this in it :)
