So I vaguely recall the entire story being inside one woman's appartment. All the other characters come over to her place to hang out, I believe with a pair being a couple? And one other male who is the love interest. I think she's quite awkward? It's a bit of a comedic manga from memory. I think she has a weird collection of items.
Cute and funny but sad that the art style changed towards the end (at least imo it was slightly different); I liked how the MC looked initially (as for fuuya, I didn't notice)
