A very very perverted tsundere-ish loli with unironically probably 800+IQ doesn't know how to say "I love you" to one of the most dense anime guys in history, so she makes inventions that will eventually rival and surpass the infinity gauntlet at this rate, just so she can see if the boy she likes has any/awaken wicked desires for her. Like she is down bad, full on wanting his kids in the heat of the moment in one of the later chapters(he still has no idea) and honestly she is pretty top tier IMO, she has a good personality and nice legs and booty that the series loves to flaunt.

Every chapter the main girl will make an invention, usually to see if the main guy has wicked desires for her. She is very kind but she tends to meet the consequences of her own actions trying to make the guy she loves do perverted stuff and then she panics/shutsdown when he is now in said perverted situation with her, he is so innocent and good natured that he doesn't even realize the situation he is often in, he is easily described as "no thoughts head empty" but he does care for her.
Theirs another 'main' supporting girl, whom is to put simply is a cute quiet glasses girl, that seems to really like the main heroine although she is lazy and needs to be bribed with yen sometimes, she is pretty fun and doesn't hide the fact that she will crumble like tissue paper under stress/difficult situations for her.
Theirs also a decent chunk of other girls, I really like the swim and track team captains(they are very nice looking and adorable). Theirs a robot version of the main girl and the robot is enjoyable and very cute in her own different way, although its hard to tell if the robot is trying to help her creator win his love but the robot definitely likes him herself.

The humor might be hit or miss for some, but you dont have to laugh to find something entertaining. I laughed a decent bit but not too much, though I find a lot of the jokes to be clever think of an enthusiastic version of meatwads ~ "I get it. It aint makin me laugh, but I get it."

It has fan service for lolicons, references, occasional sweet moments and nice girls. Definitely a series to blow some time reading here and there, avoid if you dont like lolis(c'mon embrace loliconism), panties, nonsensical logic, very very dense guys or a girl that chickens out at the last moment often(although cutely).
