I do feel bad for her a bit, but that still doesn't justify the level of melodrama she is injecting into other people's lives. She's still, even after all the background, 4/10 pitiful and 8/10 annoying.
Even the way she throws it in Aki's face and immediately runs away is so melodramatic... and now she acts like she is so strong, for finally "moving on", when she never actually even gave it a shot. And she is even aware that she didn't move on at all... Such a weird character.
