I think the GTS Touch starts of okay. You have a casual slice of life story with a little bit of goddess magic that explains why the girls are growing.
When chosing a girl to date, you are also dating the other 3 in the background. There is quite a difference in quality between these characters/stories, so experiences can vary on your choice. For example, some characters have quite a few intimate scenes with the mc like Luna & Sam, while Monica and Evelynn barely get anything. No interaction with Evelynn at her house or the pool party when she reached 10m was very disappointing.
What completely ruined it for me is when the story decided to move on from slice of life to full goddess mumbo jumbo nonsense. Girls start growing or shrinking very quickly and new goddess characters show up which makes the original roster feel less relevant.
