I actually kinda root for Harumin. I think she would treat Yuzu so much better. If I had to guess I would say Harumin will be the "last boss". Hopefully that happens.
Same here, kinda got tired of Yuzu x Mei around ch 14 I still like them but idk I just wish Yuzu x Harumin could happen in some way even if it was just for drama.
I'm sure this Yuzu x Harumin will happen. I think that Harumin will be Mei's hardest opponent in the whole story since, of course, she's the 'best friend.' And Saburouta already hinted this right? As I remember on chapter 12.5, Harumin and Matsuri had a talk and Matsuri asked her if she likes Yuzu, Harumin said no and she even cleared it by saying she does NOT have 'romantic interest' in Yuzu. Matsuri replied by saying Harumin's only trying to distance herself from conflict because she does not want to get hurt. Matsuri said that she and Harumin likes the same person, and added that 'it's female intuition' and on the same panel you can see Harumin having that lines on her cheek that you often see in a mangas and animes when someone's blushing (or maybe I'm just being exaggerated but it's there) anyway, Harumin did not said anything about that but responded by 'sigh' and saying 'whatever,' is this an indication she lost the argument and had no further thing left to say to deny it? And at the last panel, Matsuri said that she has found a crack in Harumin's shield. So I guess, the crack that she's referring to is Harumin's feelings for Yuzu that she's trying to suppress by dressing like gyaru and trying to look like a girl who does not swing in a different way?
Maybe Harumin is 'like that' but does not want to admit it because:
A) She's afraid of her sister (we all are, anyway)
B) She's afraid Yuzu might distance herself because she may not reciprocate it
C) Or worse, lose their friendship
D) She's afraid of what people might think of her
But then again, maybe I'm just exaggerating things after I saw that panel in chapter 18 where Yuzu's fan (what's her name again?) was imagining gay stuff and saying she's an avid supporter of "HaruYuzu."
Idk.
