Koori no Jouheki

On the surface, high school student Koyuki "Koyun" Hikawa seems unapproachable and terrifying to most other students. In reality, Koyun is just insecure and prone to overthinking due to her uncomfortable experiences in middle school. However, her chance encounter with two boys in school—Minato Amamiya and Youta Hino—sparks a change in her. Like her friend Miki Azumi, the boys are never afraid to approach Koyun and see her for who she really is.

Although Koyun starts spending more time with Miki, Minato, and Youta, she finds herself torn between her newfound bliss and her fear of getting too attached to others. Meanwhile, each of her friends quietly struggles with their own challenges. But as the new friend group continues to navigate high school together, Koyun and the others start to break out of their shells and enjoy their adolescence to the fullest.

The ramparts of ice
This anime has beautiful visuals, the story can still be developed further. As for the MC, yes I quite understand his behavior with the school drama that often happens being quite emotional. If you like introverted school stories or misunderstanding dramas, this one is perfect. I like beautiful openings and endings. Art style reminds me of anime you pollar lol. The character reactions look good, and the friendship development is good. Oh, the characters are pretty smart I guess? But some represent different people. The storyline is quite good, but it could be developed into a simple or more complex conflict.

Preliminary (4/? eps)

Absolutely incredible in my opinion. I watched you and I are polar opposites and that was one of my favourite romance animes and this anime is literally the polar opposite. The show feels very realistic and is really gripping. The dynamics between all of the characters so far are really intriguing and I believe it will only get better. The way this anime portrays students that build up walls against others and keep themselves locked away and to them selves is incredible. So glad that this show isn’t a love triangle because that trope is already really worn out. Can’t wait to see where this ... story goes

Preliminary (5/? eps)

The male MC, Minato comes off as a self-righteous playboy who constantly inserts himself into other people’s lives, not out of genuine concern, but to feed his own ego. Both creepy and disgusting.

It feels like the lowest form of narcissism disguised as “kindness,” which just made him pathetic and unbearable to watch.

The female MC deserved better writing. She’s portrayed as weak and apologetic for simply being herself, which is frustrating and uncomfortable.

On top of that, the show completely misses the mark on depicting the reality of school bullying. It feels shallow and unrealistic, lacking any real depth or understanding of the issue.

Overall, it’s a poorly ... written story with unlikable characters and a weak message.
