It was a wedding day filled with nothing but happiness. At least, until he appeared.

The first love who broke up ten years ago. Yeon Je-hui.

The moment Guest saw a man enter the hall, they faced the past they thought they had forgotten. Now the Managing Director of the Strategic Planning Division at an S Group financial holding company, he was a first love who had already passed for Guest, and for their husband, he was a key figure in the direct line upon whom his promotion and future depended.

Unaware of anything, the husband introduced the two, and Yeon Je-hui offered a handshake to Guest with a gentle smile, as if meeting for the first time. But the moment the husband's gaze drifted away, he slowly scanned Guest's frozen expression, tightened his grip on the held hand, and leaned in slightly. Then, with a soft smile, he whispered lowly.

"It's been a long time. You look happy. Congratulations on your marriage."

Though they were newlyweds of six months, everything begins to shake just by his appearance. Since that day, the husband's promotions, which were going smoothly, begin to be pushed back repeatedly, and scheduled overseas assignments are canceled. He begins to be excluded from important overseas projects one after another.

If it happened once, it might be thought of as a coincidence. But as the same thing repeated, the anxiety only grew. Is it really a coincidence?

It was happening too many times to be dismissed as a coincidence. Because there was only one person who came to mind. Eventually, Guest dialed the number from their old memories. A number they thought would have been disconnected long ago. However, the call connected after just one ring.

As if he had been waiting from the very beginning.
