Is this really even NTR? I mean... I dunno if it's established if the perspective character is/was in a relationship with the girl, and I mean it's called "from a Friend's perspective" so really, it could just be them watching her slowly get fatter with time; maybe they had feelings and she knew about them, but then, as she said, they 'took too long'!
In fact, if this particular comic did continue on, I could totally see the perspective character professing to her eventually!
@LurelightDevil It uses all the cliches of NTR. You don't need to be in a relationship to be NTR'd, it's just about having someone you value taken from you.
@Ashamed.boi Circle Athletics girl is likely already finished. They mentioned that part 10 is either the last part or that there is just one chapter left.
@lelleck9 saw that, pretty sure they were saying there's one more to go, which would make more sense since it would be weird to end it where it is now.
