Let's get this out of the way - this manga is not very well executed. We have a large breasted girl who chases and annoys her 6 foot hunk of a senior. The senior is aloof and is, for the most part, a blank slate of a character. Apart from his physique, he has no traits that make him standout. The manga proceeds with their interactions and features a side-cast of characters whose main function in the series is to 'make' the protagonists a 'couple'.
What makes this series inferior to others is that the humor is very juvenile and clichéd. Let's take a few examples:
1. Senpai likes cats. Uzaki tries to catch a stray cat for her senpai. She gets stuck in a bush, exposes her panties. Senpai tries to untangle her, passer-by's think they are having doggie-style sex. hahaha.
2. The gang goes to the beach. Senpai has to crack open a watermelon blindfolded. Instead of cracking the watermelon, he grabs Uzaki's breasts. hahaha.
3. Uzaki wants to try alcohol for the first time. Senpai acts as her chaperone but she gets drunk anyway and ends up at his room. She pukes on his mattress. ewww/hahaha.
4. Senpai visits Uzaki's home. Senpai, who likes cats, glances one sitting on Uzaki's mom's lap. Uzaki's mom thinks that he is staring at her breasts. hahaha.
Now such humor in itself is not a bad thing. Heck, there are *far far* worse ecchi manga out there that cater to the male fantasy of boob or ass-grabbing. What makes Uzaki-chan unremarkable is that the characters don't seem to have any emotional connect with each other. To understand this better, take the equally (if not more) popular manga - Karaki Jouze no Takagi-san. It has a similar premise - Takagi teases a boy that she likes. However, beneath the teasing lies affection - Takagi makes it very clear that she not only enjoys teasing him but she also likes helping him (e.g. in his studies or cycling skills). She compliments him and occasionally let's him 'win' at the teasing. And so, the boy despite disliking the teasing, keeps coming back to her. He inwardly confesses that he enjoys her company. She is thus his friend, a romantic-interest, and a tease all rolled into one. Thus, as readers, we get a relationship that is both playful (in its teasing) but at the same time sweet (in its emotion).
Uzaki-chan wa Asobitai lacks this emotion. The characterization is stiff, the teasing comes across more as annoying and Uzaki's intentions seem unbelievable. I personally feel that if a girl is willing to expose herself to the man she fancies, this girl should not have difficulty in telling this man that she likes him romantically.
So, do I recommend this? Not really. Unless your humor preferences are positively correlated with disproportionately large breasts, this is not that great. Mind you - it's not horrible. It's just that, compared to other manga whose main theme is to show a playful relationship between the two lead characters Uzaki-chan is mediocre. And why spend your time in reading something mediocre when there are much better alternatives out there?
So here are my recommendations - read Takagi-san or Shogi-senpai if you want a similar theme but with younger characters. Read Kawaii Joushi wo Komarasetai if you want a similar theme with an older slate of characters.
