Be Arrogant (2014)

Has the gf meets the ex girlfriends and theres 4 instead of 2 it's pretty funny and light hearted it reminded me of it
Has the sismance if u want a longer series I guess this is it.

both have good female characters who have a second chance and build the life they wanted

Both are about fashion, and have strong heroines; I do I do is about romance while Be Arrogant is more about friendship, but they give a similar vibe
