It's forbidden ( Bowuigi )

Luigi had always been in his older brother's shadow, though it's obvious why. Luigi is shy and anxious, while his older brother Mario is brave and adventurous.
After Mario has been saving the mushroom kingdom from browsers talons Luig has been left in his shadow.
Being compared to his brother is taking a toll on him as people always tell him people don't hesitate to tell him he is a pathetic coward compared to his brother.
Although soon he meets someone who doesn't mind if he's a scary cat or his brother's status he meets someone that only cares about him, for the better or for the worst.
