Everytime I see a new shoujo manga I'm like " Oh man I don't know , this is getting to be too much" *reads it* "Wow that was refreshing and fun, follow."
As it turns out, out MC befriends the maids and butlers, and even gets them to let her help with housework because she's bored, he gets interested in how his house got so much more homely, and, comfortable?, his mistress gets dumped, he then tries to win our MC's heart, but she still thinks the fake marriage is still on and doesn't get it.
wow that sucks for the mistress, like they were dating for 6 or 7 years, and he just goes for another girl just coz his house looked comfier? thats kinda fucked up, well i mean guessing by the circuntansces it looks like they probably have a more physical relationsip but still
