A
Male Protagonist who was introduced as Not
charming,
popular, or
being bullied ( not so much of a being bullied though), but as the story progresses on
he was changed and became a cool person. As simple as that, I dont care whether he was a student or a an alien as long as it fits my description.
Spoiler (mouse over to view)
PS: Or just give me same manga close to my description becoming clever or smartass well be accepted.
