Lee Sungjong is having what you might call an identity crisis. He's just tired being the girly one. He's a man. A pure one hundred percent manly man. He is fully capable to be the prince charming. He can totally sweep a girl of her feet. It's just too bad that he never gets the chance prove it. Sungjong himself is not quite sure why most girls just friendzoned him. Maybe it's because they don't think he's capable to be the man of their dreams. But Sungjong is not going to have any of that. He is a fighter. He will prove, even if it's just to himself, that he is capable to be the perfect date, the perfect manly boyfriend.

And how is he going to do that?

By going on a practice date with his twin sister.
