just finished Love Timing/ Yes, I Do both season 1 and 2, I enjoyed it much better than Heart Signal! from the format program, the screen time distribution of members is fairer, and more even than the Heart Signal. highly recommended! the only bad thing about this show is the obvious PPLs everywhere, just skip skip skip :D
