So the manga I'm looking for is about a poor noble girl, that gets an offer from a duke to be his pretend wife, so he can get is parents off his back about his commoner mistress. The MC live-in the main mansion and the duke lives with his mistress in a side mansion. The MC likes this arrangement and thinks the couple is cute. The MC likes dressing in very casual and non-fancy clothes and likes helping the servants with cleaning and chores. All the workers like her, eventually the ML starts to get more and more intrigue with the Mc and eventually falls in love with the MC. The mistress continuously tries to see the duchess but the butler tells the mistress that she is sick. When the Duke professes his love to the MC, the MC says straight out that this was not in their contract. If you know what this is and could tell me, I would much appreciate it. (●'◡'●)ノ

Maybe its this one?

Hehehehe I love the FL (≧∇≦)/
I'm looking for any yaoi that has an older brother as the top and his younger brothers friend as the bottom. Specifically the seme should be over protective of his brother and not like the friend but eventually falls in love with the friend. I know it's specific but I really want to read anything like this, please!
Omg this sounds exactly like this Chinese bl ' advanced bravely" only the 'top' is protective of his sister and falls in love with her friend/ crush ?
It's a show, sorry not a manga..
