I Am on a Mission to Save the World With My Coworkers

Seo Ji-Wun goes to pay his respects at the funeral of his team leader’s father, who is also his coworker and boyfriend, only to discover that he is married. Just as he is seething with rage at the realization that he was merely someone’s mistress and resolves to find a better man, his eyes lock with those of his coworker Sin Jae-On… and, as if by magic, time stands still!

[Congratulations! You two have been selected as the first pilot couple for the [Human Preservation Project]!]
[Mission: Restart the frozen world through physical contact between the two of you.]

We can’t leave unless we complete the mission? Here? At my ex-boyfriend’s father’s funeral?! More importantly… we’re both guys…!!
