The boyfriend in the story, as website Tech In Asia pointed out, seems like a jerk. He's not nice to his girlfriend when he loses in DotA and does things like makes her bring him food and drinks while he plays. All he thinks about is DotA.
DotA (Defense of the Ancients), of course, is a mod for Warcraft III: Reign of Chaos and Warcraft III: The Frozen Throne. Valve is working on a sequel, Dota 2.
Since the story does not give the couple's names or location, it's possible that this is simply an internet fabrication. Made-up internet stories that are as engaging as any TV soap opera are not unheard of in Asia.
The girl is supposedly desperate to win back her beau from DotA that she is apparently planning on challenging him to a winner-takes-all match. If she wins, her boyfriend must quit DotA forever.
The girlfriend is supposedly boning up her DotA skills by training, taking notes, and studying up online for tips. Her goal is to end his DotA addiction and get back the guy she fell in love with. Hopefully she won't lose herself in the game in the process...
While the story could be made up, it is kicking off all sorts of interesting discussions online in China. One reader poll on website QQ Games (via Tech In Asia) revealed that 30 percent of those responded would give up their significant other for DotA. Moreover, the poll revealed that 80 percent of readers "sometimes" or "often" play DotA so they won't feel lonely. And here's this guy—real or not—who apparently has a girlfriend so keen to win him back over she's ready to kick his ass at DotA. If she's real, I wish her luck.
