There's not much shown about Hiratsuka's past but during it has been hinted throughout the series that in her youth, Hiratsuka was as much of a loner and antisocial as Hachiman was and she's been shown to lament it.

It has also been hinted she has been hurt deeply by her friends in the past and that she doesn't want Hachiman to have the same fate happen to him.

During her university days she used to be in charge of starting the fire for bbq/campfires when out with friends. While she's busy tarting the fire, the couples in her group started to do their lovey-dovey stuff that would irritate her showing she was already upset about being single. Shizuka states that it was her own "miscalculations" that led her to this single status.

In Volume 2 she hints at a past lover that just used their relationship for a place to stay and when he left he took some of her money and furniture.

In Volume 10 she mentions she didn't actually study to be a teacher (dialogue and her lab coat hint she might have wanted to be a pharmacist).
