Hi, this is a Korean drama from around 2017/18. 

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
