Hotaru's Light Vol. 6
Hotaru and Buchou are no longer living together 
and although they may not be aware of it (well, Buchou only; Hotaru is aware of it), they miss each other terribly.Hotaru is thinking about marriage with Makoto-kun. She wants it but at the same time, doesn't. But again, she thinks there may never be another chance in her life.
I may be re-watching/re-reading too much, but this manga is in several aspects so similar to [b:Nodame Cantabile, Vol. 1|1261277|Nodame Cantabile, Vol. 1 (Nodame Cantabile, #1)|Tomoko Ninomiya|https://d.gr-assets.com/books/1388819507s/1261277.jpg|1250120]. Specially in the chapter where Buchou comes for a visit with Hotaru's nephews and is shocked with her messy living room. I mean, he even kicks her! Just like Chiaki does to Nodame when he visits her in her department. And her clothes full of mushrooms
. And like Chiaki, Buchou cannot stand it, being the tidy man he is, and cleans up everything. And then sits down to drink a beer, like old good times 
Waaa, I miss Nodame....
