Then he should NOT call it a 'lovers' route. I think NTR is funny and go all in on an NTR route. However I do like to play all paths and on a 'lovers' route the supposed 'lovers' should only have eyes for each other. Just like on a NTS path MC is only trying to slut her out. There should be differences and they should be wide enough that you feel you are going down a different path. Right now on the 'lovers' path I know she thinks about the other guy and likes it. Which is complete and utter BS for a 'lover' and just feels like NTR path 2.
Truthfully all routes will be an off brand or full on NTR path. Your not wrong in this either. A full distinction of different paths and routes should be available and if NTR is unavoidable it should be clearly stated as such. Sadly most games do not share that and we end up in situations such as this one. I get NTR is the theme of the game but if I'M going a non-NTR path then it should be non-NTR, not just a semi-NTR path. I enjoy this game and what it offers BUT depending on how it progresses with their characters and the story I may drop it. Playing a game with a falsehood that ends in a lose-lose no matter the path I take isn't my taste. Don't say I have a choice and then have all paths lead to the same road.
