Not the best due to various reasons not creating a good setting. Like to much 4th wall breaks, character faces or reactions or terms/words ruining the mood, or simple the adult cgs not being the best (like body from an angle you can't see much, or nothing at all).... i mean, jut look at the global achievements.... anyone started route's % - ~10% = % of people who managed to read the whole route....

As many others said, if you plan on playing all routes, leave a certain purple haired girl last. Of course, some say she is the only one worth but whatever, all of them have good moments so I don't agree, though still can't say they are amazing...

Uncensored (no mosaic). Adult patch is needed and you can't tell if it worked unless you start skipping half of the common route until you see girl nipples. Though if you get to said scene and nothing, you know patch was not added correctly

Heavy on the comedy with the romance being an accessory that it loves to keep reminding you of.
Honestly I wouldn't say this is a serious romance at all and is almost nonsensical. Its very much normal everyday stuff but with four heroines forcing themselves down your throat constantly which can get tiring.
The writing isn't half bad with some genuinely funny moments and the characters themselves are moderately tolerable. Shione, the silver haired girl, makes constant use of a catchphrase which I found a little adorable.
Definitely worth a read, just don't expect anything heavy in terms of plot.
