Seven Sundays

Tae-Yang thought he'd never see Ji-Wan again after their messy breakup, but fate and the media have other plans. Now a heroic firefighter with a documentary deal, Tae-Yang reunites with his producer ex at the broadcasting station... except Ji-Wan is doing everything he can to avoid him. But then, why does he have a seven-year-old kid with the same name as Tae-Yang? Once he secures seven dates with Ji-Wan as "payment" for using his name, it's up to Tae-Yang to do some detective work and win over his reluctant ex in seven Sundays.
