The plot is entirely poorly done and the lines of the characters are cringe.
The whole story that goes on until the protagonist gets along with the three girls is skipped, and simply introduced as a kind of "recapitulation" without further explanation.
The characters are superficial stereotypes.
Basically all the girls are virgins, but completely nymphomaniac and without any shame, which leaves a lot of doubts about how they were still virgins so far, and also not behavior according to people who have never had sex before.
Apart from the common stereotype of the characters, there is absolutely no deepening in their history or in their personalities.
In explicit scenes
they behave in exactly the same way, except in the final scenes where each one wins a small "exclusive" scene.
The animation sucks, the mouth movement is not synchronized with the moans and speech.
The movements of the characters is very artificial, this totally breaks the immersion.
Explicit scenes are completely repetitive.
And personally I was annoyed by the hysterical cries of the characters for no reason.
This anime is a desperate attempt to make money with very low quality content, I do not recommend it to anyone.
