I have to disagree with your assessment craptree. I personally don't think Tan Jiu writes a great slice of life story. My reasoning is because the characters don't have depth and are not memorable. In order for those characters to have depth they need at least a few chapters and not just 4 pages devoted to them; then, switching to another character which makes the audience have less connection with the characters. Slice of life generally doesn’t need a heavy plot but what make slice of life manga/anime good is the depth and how memorable the characters are.
I can't even remember glasses guy's name or the big heavy guy's name.(I have seen other people refer to glasses guy as glasses guy) They are not memorable characters unlike the characters from Nana such as Ren, Yasu, Nobu, Shin and Takumu. I remember these characters because they had a back story and the author devoted time to make the audience have a connection with these guys. I know Nana and Their story are slightly different genera’s with Nana being abit more serious tone and Their story a comedy but I don't know anything about these side characters. The only person who looks like getting a bit more time put into the story is Qui Fang. This is a good thing if the author could now devote time and focus on Qui Fang, instead of jumping to different characters all the time it won't be as off putting for me. Plus, narrative wise it would be stronger and the audience can actually form a bond.
I know that Their story has more chapters to go and hopefully it can devote time and effort to these characters and flesh them out. Plus, not switch characters after 4 pages all the time. Of course, the author should expand on the universe and not just focus on yuri. However, the author should stop switching between the characters all the time. It’s like a baby that has short attention span that plays with one toy and immediately switches to another because it’s bored. It’s frustrating as an audience keeping up.
