Taeyang never thought he’d run into his first love, Jiwan, again—things didn’t exactly end well after Jiwan ghosted him years ago. So when Taeyang’s heroic firefighter rescue lands him a television appearance at the very station Jiwan works at, Taeyang seizes his chance. But no amount of imagining their reunion could have prepared Taeyang for the revelation that awaits him…Turns out, Jiwan has a kid—named Taeyang, no less! And after Taeyang learns Jiwan’s son is as old as their breakup, all the pieces start to fall into place. Now he knows just what to do: compel Jiwan into giving him seven of his Sundays for seven dates to make up for all that lost time!
