anyone watched j-drama densha otoko? it's the japanese name for "train man".
This is based on the true story of a man who has not been attached since the day he is born. He's known as an otaku or a nerd. He's also portrayed as a loser in work and family as well as everywhere he goes, being bullied by many. And he has been longing to be attached for a long time until he met a beautiful lady he met in the train whom he rescued from a drunkard. From that day onwards, he had been dating the girl using tips he got from friends he hardly knew from the internet website for singles.
I think this show is very realistic. But I have to admit it's a really funny show because I have been laughing all the way.
