I really like this one. It's pretty fresh. You may think it's just a classic harem with a good but dense boy. You are not wrong but there is a twist.
The mc is not the boy it's the girl (or girls).
This change everything. The girls wants him to fall in love with them so they are going though character arcs to change little by little.
Simply put it feels like a shoujo drawn by a man.
Man every harem manga is usually about FMC'es rather than MC's. MALE leads in harems er usually the same cardboard cutout. We get almost always the same, sometimes MC's are overpowered but their general gist of morality is from the same place "kind", "good" and etc.
You know what is the difference between shoujo(josei) and this? Female oriented mangas usually make normal men angry. Almost every shoujo that i have read made me angry. Women act like streetwalkers and are still considered "good". They are freely being flirted by other men while having actual relationships and they do not retort those advances and play "dense" cards same as shounen Mc's. Guy touches your body all over and she still doesn't think it's considered cheating with her boyfriend.
There is clear distinction between shoujo and shounen, when boys read shoujo they get feelings of disgust and anxiety(according to me and people with whom i spoken to) i do not know if girls feel the same about shounen but my general feelings didn't change for over 20 years. With age i came to dislike shoujo even more due having more morals during my later stages in life. Josei and Seinen both at least mellowed down gender specific idiotic, imbecilic fantasy troupe's but they still exist and live on.
Shounen and Seinen harem mangas where female perspective is more prevalent is due to simple fact of POV porn. It's easier for the reader to "feel" that they are MC if he isn't shown much nor if he shows much character. Then they add all kinds of girls to suck the losers dry and they start to ship their "favorite" girl i.e. Shipping the same fucking Archetype in every fucking harem manga....At first i thought it was because "all men dream about harems" then i understood that in actuality not many men want this, its damn hard to deal with one woman in your life it becomes a nightmare dealing with more, unless you are a muslim who can suppress a woman with religious laws. (But even Quran states in order to have multiple wifes you have some heavy obligations)
