Man, this was such a nice visual novel! I like the twist where we play as the yandere and we see how different of a yandere Arlon is comapred to most yanderes. He's quite reserved, cold, and methodological. Yet, despite his cold demeanor he can easily be shaken up and driven to hysterics. I like how he was able to calmly and quickly gain access to Owen's house like it was no problem, showing just how many times he's done this and the way he goes through the house, always having a story to share that one other character doesn't even know about... It was by far the creepiest part.
The design of the characters are quite simple but interesting, especially with how Arlon looks to be dead and apathetic, only emoting whenever Owen is brought up, Owen looking to be such a normal yet pretty dude, Lyra looking unhinged even when she looks to be comforting or seducing a vulnerable Owen, and the maids one looking serious yet knows how to read the room and the other looking to be an airhead. They all look the way they act, and I'm super curious if Arlon fights against other yanderes like him that aim for Owen's heart, because if so, that would be interesting as I haven't seen that before!
Amazing job! Looking forward to the update and continuous development!
