Yeap, I know it's kinky. Games I found here broke my moral compass lmao.
Honestly, you do the slowburn romantism SO well (especially with petra, juna ,and that sun goddess girl I can't remember the name of) that both characters teases each other with flirts, relationship goes back and forth between them sometimes gets bumpy, further plots reveals many things about them and their history while strenghting their bond steadily and you see them maturing in real time, what I'm trying to say is even if there was no kinky content, game would be pretty satisfying anyway imo. Because game doesn't need it to be interesting (some kinky content adds flavour tho).
That slowburn romance is something many games try but very few able to nail it, and you my friend bullseyeing it. My only critism would be that; Petra always felt like the main girl for me during the playthrough, I found that crossing the red line with her, was kinda.. underwhelming lol, I mean it was about some bet or something if I'm not wrong, it just goes so well until climax and then theres no climax at all? I dunno. Just another friday night xd.
