It's an unique experience for the first playthrough, but the impact is gone on subsequent playthrough because:
1.Only one girl does this.
2.You get the sad girl scene regardless of you chasing her or not.
3. To get her ending, you have to never have sex with anyone during the entirety of the game e.g. not playing the game. And she keeps showing up after every single sex scene with any girls even when one sex scene is enough to disqualify you from obtaining her ending.(There is other girl that requires you to only ever having sex with her but she doesn't guilt trip you if you don't chase her.)
