"Ever since I could remember, I’ve seen the threads. It’s not really something I can talk about with others, but I see them wherever I go.

Legends say that we are born with a red thread tied around our pinkie fingers. Each end is connected to one half of fated souls...or soul mates. The string can stretch and tangle but it will never break. I’ve seen them stretch across oceans and skies. The thread does not care about what is convenient for the lovers, it simply follows destiny."

Yee/Lee Nami is your average college student struggling to pass Physics and trying even harder to find her one true love. Oh, I forgot the mention that she can see the red threads of fate. She gets a bit tangled from time to time, but she's always been on the look out for her other half. What is she to do when she finds that he and two of his friends have created a huge knot in their threads? What's worse is that she still can't tell which one he is.

Is he YongGuk? the boy helping her pass Physics.
HimChan? the playful boy trying too swoon her.
Or is it Zelo? the boy she swore she wouldn't date because of age differences...but still, he declares his undying love.

Nami has to figure things out before people around her get hurt and try keeping her secret under wraps.
