Hey manga lovers
Help me find a manga . I want re_read it again but couldn't remember the name of it . 
It's sm**, historical, straight ..........
It's about a girl she married a man but they are not in good relationships. But she wants to get fuc*** . So she haired a male sl** ... And it was her husband . They were wearing mask but the husband knows that she was his wife .. and this goes on for a long time .. eventually they find out about eachother . They lived a long happy life after that . 
Another story I remember 
She sent a letter to her husband and in that latter she sent her underwear it's like she is calling him to come and fu** her ... 
Um sorry if the story is messed up. 
I remembered little bit of it . 
Please help me find it .
