Nega-kun and Posi-chan

Story:

Hoshi Sayaka and Nega Shouya are high school friends. Hoshi is very optimistic, whereas Nega is incredibly pessimistic. They are both madly in love with one other as well, but they entirely misinterpret each other's signals—he by flaw, she by excess. These two polar opposite young lovers are not the exception to the fundamental rule of magnetism that asserts that opposites attract!
