A coincidental meeting (우연한만남)

A chance encounter, or perhaps a chance encounter, in our lifetimes. Yoon-ha (the female protagonist) and Tae-hyung (the male protagonist) are each other's fateful partners. Yoon-ha, who has a wealth of dating experience, and Tae-hyung, who has no dating experience, share a young, accidental love story. Would you like to take a peek into their story, beginning in their teens?
