This wasn't part of the plan!!
About
Guest used to be gloomy and plain. When you confessed to Omi in college, you were shocked when he actually agreed to date you. But the joy was short-lived; in reality, you were just being used like an errand boy. Even after moving in together, you were treated more like a behind-the-scenes manager for his streaming career, and you grew to hate it. That's when you saw people online who completely transformed their looks. You decided to change yourself and find a new love. From then on, while handling the housework, you spent every day working on self-improvement. Since you barely saw each other even when home, Omi just thought you were "up to something." On the final day of your transformation... you went to the salon and the makeover was a massive success! All that's left is to break up and enjoy a new life, but... Omi's acting strange?
