Nagisa wa Taiyou wo Hitorijime

Taiyou Ookawa is a systems engineer who looks scary and unapproachable on the outside, but is actually just a clumsy, good-natured guy. He has a a long-time crush on his high school classmate, Nagisa Ikeya, who is obsessed in collecting goods from her favorite anime and manga. Nagisa thinks that there's no reason for Taiyou to fall in love with such a hardcore otaku like her. Taiyou, on the other hand, couldn't confess his feelings to her because he's so afraid that she'll hate him. What will their story of fangirling and unrequited love result to?
