'Unkind Women' is airing right now and I'm thinking it's like this. Maybe it's a bit makjang with the plot twists but still. The women in the series have their own circumstances: a grandmother meeting the woman her husband cheated her with (and somehow striking an odd friendship with her), a mother continuing her feud with the teacher who kicked her out of school, the daughter caught in love triangle with this teachers sons, the single and established aunt struggling with her age and work... Especially with the grandmother's plot, I'm feeling that "unique" bit.
'Let's Eat' is a really lighthearted, funny one. Single people, neighbours, their life and food. The romance is there, and it's comedic, but it's not that kind of PSH-thing you want to avoid.
'Best Wedding' has mature themes pointing out the patriarchal society and struggles of single mothers. Not that kind of slice-of-life drama like 'Misaeng' but I think you might like it.
