Manga Karakai Jouzu No Takagi-san
This is easily one of the most adorable manga I've ever read. No drama, no saving the world shenanigans, no harems, just a girl who shows her affection by teasing the boy she likes.
The best part is easily the interaction between Nishikata and Takagi-san (and to a lesser extent their classmates). She has him dancing completely to her tune, usually through a carefully chosen word or innuendo. Meanwhile Nishikata himself is determined to get one up on her, but he's often his own worst enemy due to not thinking things through or allowing his own paranoia to get the better of him.
If you're having a bad day, or are just tired of anime with high body counts, give it a read. You'll probably be laughing halfway through Chapter 1. And probably rooting for them to get together fairly quickly, because you can tell that even if they get together, she'll still tease the life out of him.
Manga A Very Genuine Feel-Good Series
Takagi-san captures all the sweet nostalgia of awkward middle school love through its delightful leading duo and grounded, whole-hearted writing. A charming manga series to enjoy leisurely, and the anime delivers as well, featuring a picture-perfect voice cast and whimsical soundtrack to bring the story to life.
The strong chemistry of the two leads is readily apparent through a variety of mundane but adorable exchanges between the two. Every scenario follows a simple formula of Nishikata trying to get the better of his classmate, only for Takagi to unfailingly, and humorously turn it around on him. Despite its predictability, no scenario ever feels boring or dull as the lovable Nishikata and ever surprising Takagi consistently make for entertaining encounters.
While simple, Takagi-san is a delightful celebration of youthful innocence, and is a must for those looking for a feel-good series with a lot of heart and a teasing charm that will keep you coming back for more.
