At first it felt like fixed version of "nega-kun and posi-chan". MC is not stupid, FMC has adequate chest size, and everyone is adequate.
At the end it felt like ideal version of romcom, "as they all should be". Guy and girl talk normally to each other even when they have some feeling for each other. And yeah, that moment when he asks her contact info without blushing. You know, after all those standard romcoms it makes a big impression, lol.
I also would like a serialization, but on certain conditions. First, they have to start dating by the end of volume 1. Harsh, yeah, but it's like this. Second, no harems, ntr or other pointless bullshit. Third, drama should be treated realistically, as if it happened IRL. They shouldn't be geniuses who know everything and how to act in every hard situation that life throws at them, but damn, I expect them to behave like highschool students who have brains. I guess it can even be interesting then.
Under these conditions, I think this will make out as serialization. Anyway, mangaka is talented, good luck to him in everything (s)he will do in the future.
