Sorry I know I ask for recommendations a lot but it's easier to find the hidden gems this way that I might not otherwise consider watching.

Anyways I'm looking for something similar to A Gentleman's Dignity. Something about a group of male friends and the women that they have relationships with. I'd prefer it if the guys were in the 25-45 age bracket.

My Too Perfect Sons
Better Man

If you are interested in the reverse also (group of women and their relationships):
One More Happy Ending
Unkind Women
Thank you, I'll have to check out the first one. But I'm just looking for male friendship + romance. Even if the friendship isn't the focus like in Oh My Venus and The Gentlemen of Wolgyesu Tailor Shop.
