Song Na-Young, a 29-old-single mom, goes through the baby care with help of three best friends of her late husband. Na-Young, born with natural optimism and somewhat recklessness, just lost her husband and depends on three distinctive characters. Han Su-Hyung is a competent fund manager and most successful among friends, but most narrow-minded and stingy. Gwanghui is a handsome cartoonist with good taste of fashion, but an ultimate cynic.
