I'm also looking for one more manga. The main leads were in college and were neighbors. The female lead was very messy while the male lead was neat and a very good cook. The female lead started learning cooking from him. Later on it had a sequel where they both moved in together and had started working.
I was searching for another manga but I accidentally found the one I was looking for here's the link if you are interested(≧∀≦)

I don't remember much but I think the male lead could see the ghosts while female lead could hear them. The ml was kinda obnoxious at first but the female lead said that to his face. And female Mead's friend had a restaurant.
