I didnt get any doki doki feeling from this manga
I can already predict that FL will infatuated with that hunk, a rival appears, somehow they'll turn apart because a misunderstanding, then big bro will coming in town, big bro want a piece of that ass, FL have to make choice between 2 sausages, etc etc
And ofc dont forget to mention how big he is down there, such a hunk, rough but also tender in making love
