@jokerxhisoka I don’t think the goddess was just trying to solve her problem of getting Nogata back.
I think she was, at the same time, trying to get rid of her indecision in their relationship.
If you look at when she said “What am I supposed to do?!” in chapter 4, the goddess responded, “isn’t it good? even if it’s not displayed now.”
By sending her to an alternate dimension where she’s not dating either Nogata or Motoasa, the goddess is giving her the chance to pick between them once more.
This time, though, it’ll be a more stable, thought out decision that doesn’t lead her to be indecisive in the end
Sure, it may be a bit over excessive in order to teach a simple lesson, but she’s a goddess that’s probably lived for many years with knowledge beyond the concept of time (knowledge about alternate universes, ability to control human minds)
She’s bound to be a bit eccentric
She could’ve just made Femc pick a boy by altering her memories, but the goddess wanted femc to decide for herself for whatever reason and she’s sticking by that.
I guess my main point I’m trying to make is that the goddess wants the femc to come to an understanding of her own feelings. While her process is over excessive, it makes sense coming from the goddess, seeing the goddess’ eccentric behavior.
