The problem is actually quite simple - The mangaka could not figure out a way to draw out the romance between the two leads without having them act like idiots. Okay, mostly it's the male lead acting like an idiot, but veteran manga readers will know exactly what I'm talking about.
That being said, it's not all bad. There are some parts that are interesting, but there are also a lot of parts that are pointless sex scenes in terms of plot and frankly kind of boring for their "h content". If you're going to have a pointless sex scene, at least make it good, right?
If you can stomach a male lead that is probably the pinnacle of the typical shonen wuss protagonist, and I'm not saying this lightly, he's a complete waste, then you might get a decent amount of enjoyment out of this manga - but chances are you'll probably be perplexed at phenomena as to why he can't seemingly shove a 80lb japanese girl off him, or how he has the inability to say things like "Hey, get away from me!"
