So I just finished this manga because someone posted this on r/manga. It was a nice read and I really like the story.
Now that's put aside, I want to address your criticism
@InsertName. I'll go point by point:
[ul]
No, despite its premise and its author, it's actually not a Yuri manga. But I could definitely say that Ran could very much have feelings for Keiko-senpai. Despite how Keiko talks about Ran, I couldn't say she reciprocates the feelings though. Ran came into her life in a time where she needed it the most and it definitely fill the void in her heart. But that's not necessarily leads to any romantic feelings, at least from Keiko. You might say then that's bs, but to me it just shows how nuanced the story in portraying human emotions.
Next, why did she move? From what I've interpreted from few chapters before, an earthquake happened. After the earthquake Ran got news about her dad and then she talked about how his dad's workplace is near the sea. I know that she said that "they found him amidst the chaos" but that could also very much means that they found "his body". Nonetheless, Ran now must go back to her parents house, because her mother might be alone and needs her only family left. This also explains on why she felt forced to move and wished she could've stayed for longer.
Then, why Keiko broke up with her ex? Again,
my interpretation. Her relationship with her ex actually runs pretty smoothly and we can infer that she might've been pregnant with his child. Then something happened and I think it's her miscarriage. This is why she referenced "when she can't have something, she tries to fill the void". This something that she can't have can refer to her baby or in general just a happy relationship with her fiancee. Now you might think, that's not enough reason for a couple to break up if they truly love each other. You're right, because I think the main reason is because she lashed out to her fiancee after she lost the baby. It pretty much go sour from there and he can't take it no more.
As to why she dislikes her mom? This is not as clear as the other things and it could be many things. From what I've seen, I've interpreted that her mom could be your typical "tired single parent". This can be inferred since Keiko never mentions her dad and his dad didn't show up in her flashbacks. I do say "tired" but her mom might've not given her enough attention but not abusive, since Keiko seems to not have bad memories of her but have few good memories with her. This lack of love is probably why she became a delinquent, why she freely gave her virginity away etc. But I'm still not sure what to say about the "boy" in her flashback. It's very much up to interpretation.
Finally, I don't think this series was axed. From what I've seen, the "underlying plot" flows nicely and it reaches a very natural ending. I do admit it's short though. But I think this manga has always been intended as a "slice of life" manga which also have underlying plot which you have to "read between the lines" to find. It's a really great storytelling, at least for me. I love Keiko and Ran, their characters and chemistry between each other are so believable even compared to actual yuri romance manga.
