manga with a sweet, shy, pretty girl and a popular guy who keeps bothering the girl and said " i will make you fall in love with me" after that... the girl is slowly falling in love with him without her knowing her own feelings.-------> and then they have to face many obstacles to protect each other.... something like that
anything similar with this is ok
or any kind of manga with shy and popular boy is fine with me too
You, miss, have some pretty cliché kind of taste, i'm surprised that you didn't want a "Older male, younger female" relationship too. (pay no attention to that, i'm in a bad "internet fight" abstinence and i need to release some stress)
Anything under shoujo. Honestly, the average of shoujos are all like that.
According to description, the to date best selling of what fits the description would be Boys over Flowers. I read it, kept pissing off ><. You'll probably like it though, it fits what you said perfectly and I'll admit it is better than the others with the same plot.
Well otherwise, there's hundreds of those types of manga. Link
