“I never imagined being here and doing this with you.” 4f4x5

Shim Woojin was Kwon Kyung’s sunbae back in high school. 12 years later, they reunite at Woojin’s best friend’s wedding... who just so happens to also be Kyung’s first love. Kyung always thought of Woojin as his rival in the race for his best friend’s affection; but as the two of them find themselves reconnecting at an after-party all alone, their conversation isn’t the only things that grows deeper and deeper...

Note: The title seems to be a wordplay, as it makes use of the first syllables of each of their names, similarly to how couple nicknames are used in Korea (while the word 경우 means cases/circumstances, 경 by itself is the writing of Gyeong and 우, that of Woo).
