Most of the low rated ones have toxic couples

Nice! I Appreciate it :)

I totally agree that the toxic ones are low rated,,, that's why I do not trust too much the rating since I'm able to find one that I really like to give a high rating.. I'm so grateful to you giving me those list.. really thank a bunch hahahahha
