People going social justice workers over this when the whole NTR thing is just a big gag and the MC won't really go for it. Also, this artist has done multiple works of harem-ish polygamy, in which YOU people are actually into, the MC has one girlfriend and now some homewrecker is coming and YOU people are like "Woah, girl 2 is hawt" and now the tables turn and Medusa is getting harem, "fuck man, 1 star hurrdurr unloyal hoe, begone". It's a comedy, people. You're supposed to laugh at it, not jerk at it.
