Hi, this is a Korean drama from around 2019 .

I think it was 3 episodes by 3 different teams but the first episode was amazing. A young woman had 3 boyfriends and I think she wanted to change her life - was there some counselling or something involved - and she split up with all 3 at the same time. 

One was for her being looked after, one for sex and one for friendship and in the end she ends up with number 3. There was a great line in the breakup scene when number 2 told her that breaking up was not about efficiency.

I really looked and could not find it

Thanks to everybody who has a read, a think, and possibly a look

This drama's synopsis kind of suits your description (https://kisskh.at/49735-begin-again)

Thank you both very much. I had sort of given up. Thanks especially to you Coco, it is the first love scene  drama. 

Going to rewatch this, hopefully it is as good as I remember.

I had a clumsy little happy dance. 

THANKS

Yay, glad you get to watch it again! You're welcome :)
