Search for a hentai manga

[Tamira445]

Hi, I don't know if I'm in the right forum. Basically, I'm looking for the name of a hentai manga I read some time ago. It's about a boy and a girl who end up sharing a house because the landlady thinks they are a couple since they share the same last name. They spend the day resolving some differences and in the end, they have to sleep in the same room, where they both discover each other's taste for erotic novels. Finally, it shows that they are going to get married. I hope you can help me. I've been looking for almost a year and haven't found anything.
