Infinite, Loop

Muhwan meets Wonyoung while he is digging into an unsolved case, and finds out that she is the daughter of the woman it happened to. She runs a channel of her own and gives away little about herself. The two of them start looking for the man who did it, Namgyu. Before that, Muhwan was streaming to twelve viewers. He was talking the case through on air when a donation came in with a voice saying "I'll give you unlimited time," and after that he was stuck inside a four hour loop that reset on him. He decided the way out was to find the real culprit, which is what put him on the case in the first place. He and Wonyoung miss Namgyu several times over, and Muhwan comes close to dropping it.
