The seven ladies of A Pink are fairies of Pink Paradise. Due to a serious mistake which they made, they are banished to Earth for 100 years. During their time on Earth, they have 3 strict rules to follow :

1) Not to reveal their fairy identities as it may cause serious inconvenience to them.

2) Must be homed by 12 AM everyday as a symbol of decency.

3) Must not be kissed. (their Queen refused to tell them the reason of this rule.)

Everytime they go against any of these 3 rules, they will lose one of their five senses for a week. Adding to their struggles of adapting to being human-beings from fairies, love also starts to bud between them and their classmates of all boys.
