You have asymmetrical pectoral muscles. That's genetic and relates to where the muscle connects to the bone. There is nothing you can do to alter it. Some guys have a gap in between their pecs, some guys have asymmetrical pecs like you, and some lucky ones have no gap and total symmetry. Sorry that's not the news you want, but you cannot change where your tendon insertion points are.

On the bright side, you have the upper body of an 11 year old boy (low bodyfat and muscle), so your imbalance is very noticeable. If you continue to eat right, work out and succeed in building some muscle, that imbalance won't be as noticeable, and you also won't care about it either way.

Ouch.

Anyway, like deknoi said, it's related to your genetics. Nothing much you can do to change the shape and insertion points of your muscles, so just keep training consistently.

LOL, perhaps a little bit harsh, wasn't trying to be mean. There's nothing wrong with you, just keep up the training and don't even think about trying to focus on side of your chest.
