The Steins Gate choice!

Some time ago I discovered a series named Steins;Gate. When I started watching this, I could not figure out anything because it was very strange. But at the end everything was explained and I was surprised.

Why I'm fond of this series?

The reason it's because it has everything. There's love, comedy and some action. The main theme is the time travel. They use a phone and a microwave oven to send mails to the past, and change some facts. Only the main character knows what happened before they send the mail. But when they send a mail, they the main character changes from the alpha timeline to the beta one and he needs to come back or his friend will die.
