I'm very interested in Remi though, I feel like there is a lot more interesting things to learn about her. Like her ulterior motifs. I believe that there is something in there more than just lust and game for her. I feel like, there's more... depth. About that symbolism with the bottle on the sea, I'm not so sure what that meant. It's okay to have opinions about it, but I think it's too early to make a definitive judgement about the characters yet, considering that the manga isn't close to finish yet(or so I believe)
I remember dropping this manga a long time ago because it didn't get frequently updated and it pissed me off. But, after re reading it, I've noticed some changes in my perspective about this manga. At first, I was like, this manga is so strange, it's a total cliche sometimes but other times, it just surprises you as well. And upon re reading this, it made me look more in depth with the characters, like Remi, Meru, Ruki, Maasa, and etc. Honestly, I didn't like many of the characters, not because they are unlikable but because I feel like they are too excruciatingly realistic(my opinion). Sometimes, it's really hard to watch/read something with realistic portrayals, especially the bad parts of it. And this manga made me feel like that, icky, disgusted, humiliated and utterly baffled.
I liked that Fue was asexual though because asexuality in most mangas are so underrated, I feel like she's the first one I've ever read that is asexual. What I didn't like and felt uncomfortable reading was Asuna's lustful mind, which was definitely not a bad characterization but rather, a very cruel portrayal of a real college person. And yes, everyone of them are. Fue's got to be my favorite, not because she's asexual, but because she's complex and diverse, she seriously got some wisdom for someone who choose to look at them self as a child/kid, much like me.(and sleepy most of the times)
Maasa on the other hand, is pretty interesting too. If we shake off her weirdness, she could also be our one little miss perfect character. I especially love her confident personality and her being a hard worker. I wish we'd see more of her complexity. And other than her weird stature, she's also especially kind and blunt and helpful, and I can't wait to see more of her and Meru! Meru though, I don't find her so compelling like Fue and Maasa but I kind of, sort of, like her character, for laughs. She's a really loose-control girl and has weight issues, and I like that Maasa doesn't make her feel insecure about her weight, doesn't tell her that she's not fat, but instead, she tells her subtly that it's okay to be fat, and that it's cute. I don't know if this was intentional in her part, but that one really is good and hit right through Meru's chest.
Leaves us with only Saachan, Ruki and Remi drama. This one is pretty interesting and is also very hard for me to read. One reason is because I don't really agree with either their actions and decisions, but it's undeniably too realistic for me. I like the situation though, Saachan and Remi going behind Ruki's back(although Saachan and Ruki aren't really going out that time yet), taking advantage of her busy days to hook up, which led to conflicts between the three of them, but ended up with Saachan confessing and asking Ruki out and they live happily ever after (?). I like it because it's realistic. Yes, I said it, realistic. Think about this, it's not that easy to get over your crush, and if your crush asks you out when you know you're still hung up on them, an impulsive reaction will pull you right in. But the story is not over yet, it has only begun. There's so much more left to be uncovered. There will be more to tell about them and I refuse to believe that that's how they're going to end with Saachan-Ruki story arc, it's just too simple and too forced, there's gotta be something that will shake things up. And what about Remi, I feel like this girl has so much of her character that's left unsaid except for being lustful and manipulative. Did she genuinely liked Saachan or Ruki? I want to know so bad.
All these is my own personal opinion
