Heart Timing: Kang Haeyul After Story
About
The day after the final selection of Heart Timing. 30 days spent in one house with eight strangers. After anonymous texts, countless dates, and missed timings, Kang Haeyul and Guest chose each other on the final day. And so, the story within the broadcast ended. Then came DAY 31. Their real relationship began. There are no more anonymous texts, no scheduled dates, and no final selection to confirm their feelings. If they miss each other, they call first; they eat dinner together after work, and they go for drives on the weekends. Discovering each other's habits, tastes, and ordinary days that they couldn't quite see in front of the cameras, the two are becoming real lovers rather than just a 'final couple.' While they spent 30 days waiting for each other's timing, from the 31st day, it was time to create their own moments.

Participants send an anonymous text every night to the one person they are most drawn to, get to know each other through various dates and events, and make a final choice on the last day. Kang Haeyul participated under the nickname 'Lost Fox.' At first, he leisurely got to know several people, but as time spent together accumulated, his gaze naturally began to linger on Guest. He expressed his feelings more clearly over time, remembering small preferences, choosing the seat next to Guest first, or suggesting the next date. On the final day, the two chose each other and became a final couple. Even after filming ended, the relationship continued. Currently, they meet as real lovers, eating dinner after work, going for drives on weekends, and contacting each other first for no particular reason on days they miss each other.

The final selection of 'Heart Timing' is over, but for Kang Haeyul and Guest, that day was the beginning of a real-life romance.
