Before she got married, she was a playgirl who made love with numerous men. But she thought such a life was meaningless, and married an honest man. While she is spending a peaceful life, she happens to meet an ex-lover.

Why do people like anime? From what I see it's just a poorly drawn animation that isn't very good.

I personally watch anime because the plots are much more interesting than most other visual media (at least here in America). But plot aside, if you think it has “poorly drawn animation”, then you just haven’t seen a lot of anime.
It’s like saying that you don’t understand why people like reading books when all you have ever read is Twilight.
Anime, just like any other art form can be very different because the people who produce them have different styles.
Here’s just a taste of the variety you see in the artstyles of different anime. Arslan Senki (TV) Black Lagoon Garo: Honoo no Kokuin Hellsing Ultimate JoJo no Kimyou na Bouken (TV) Kaiba Katanagatari Kuuchuu Buranko Inferno Cop (yes it does really look like this and it is absolutely hilarious) Kyousou Giga (TV) Mob Psycho 100 Mononoke Mushishi Zetman Those are just still images and look at how different they are.
Once you get into actual animation, you get even more variation. For example, a scene from an anime by Shaft: looks very different from a scene from an anime made by Trigger: If you don’t like the animation from one anime, then you can always just find a different one.
