青い花 S1

The vibe is definitely unique, and very relaxed. I haven't read t the manga, but it seems like it was a bit of an awkward adaptation, that at times felt slightly stilted. They could have called the show 片想い. Almost everybody is in love with the wrong person at some point.

That said, the characters, their emotions, and experiences of love, are all really well portrayed. Their behaviors, successes, and mistakes all feel very realistic. The characters in general are pretty likeable, and it's very much a character-driven story. The ending left me wanting a bit more, and curious to read the manga. The two main characters are enjoyable, and quite different from each other. Fumi is a bit melancholic and withdrawn, but not held down by it. Akira (A-chan) is pretty genki, but also down to earth. You see them both grow over the series, but especially Fumi-chan, who slowly learns to be more assertive. They both care for and about each other a lot.

Language-wise there's nothing particularly unique or challenging about it. Everybody speaks at a normal pace, the speech isn't very slangy, and there aren't super long monologues or anything. Might be a good watch after you've seen a few easier shows.
