On Earth, pouring boiling water over a bowl of instant Ramen means you're hungry. On Planet Cup-Ramen, the women are human sized and the men are three-inch tall. Instant sized men need to be brought up to human size by, you guessed it, pouring hot water on them! It's also a proposal of marriage. Sumire - a lively 16 year old boy, was only hungry when he bought this peculiar looking cup Ramen from the shop. Little did he know that it was actually the space ship of the pint size Prince Kanmen of the Planet Cup-Ramen! Prince Kanmen is very persistent; and Sumire who is caught in between various fiancées, older brothers, younger brothers, obsessive SM handmaidens and pop stars, he may just end up marrying Prince Kanmen out of sheer exhaustion!
