Yoo Hyosung is a girl deprived of proper love and comfort. After yet another break up and broken heart, her happiness is placed elsewhere - on the internet.
After a suggestion of creating a dating website for those who are in need a significant other, she takes up the offer and runs her own, giving out advice, but swearing not to fall in love and break her heart again.

That is - when she accidentially encounters 3 members of 3 different yet equally popular boy idol groups through what started off as a game for the 3 boys, with Hyosung magically winning the hearts of them with her quirky personality, and plain, yet somewhat appealing appearence - ending up as a competition for Hyosung's heart.
