Kanpekina Ore no Seishun Love Come

"He's like the handsome main character of a shoujo manga."

"That's a guy who can do anything he wants."

Ryoma Godai, a high school boy, is smart and athletic, a charismatic figure who is admired by all at his school. He builds good relationships with his classmates, but because of his “perfect” persona, he doesn't get deeply involved with others and does not join any social circles.
One day, Ryoma overhears Minami Kinoshita, a classmate who has been shunned because she always acts too seriously. Ryoma tries to help Minami by relaxing his usual antisocial policy, but what will he gain from this relationship? A new young romantic comedy featuring a “high-spec” protagonist!
