This is not NTR. She went on several dates with this guy until they started being physical. Hell they're literally dating. All because there's a childhood friend who couldn't nut up and ask her our and thought a promise made when they were kids was contract binding, it's his loss. Plus she encourages him to find his own happiness. No malice in this one from my perspective.
Its not really netorare? they dated and they became sex friends the childhood friend lost bc he didnt ask her out first and thats kinda it the art is great tho def add this to my list
Wow they are sending the other dude nice blackmail material and i just hope the author gets a little bit realistic and make the other dude post it on social sites and make it viral and see their go up in flames.
And another shit mumbling about showing photos to friend and etc
Wtf
