Yeah I agree with u with the warning, even though it would spoil kinda the whole jist of the game.
Romance is simply a tool for Lillian to get what she wants, however she can't remain emotionless and static, her heart moves, but she can't follow it.
However unlike Red Embrace, the whole story was mainly about romance between Lillian and the love interests, the whole spy mission was secondary. Also thinking about it.... I can't visualise a reality where Lillian would form a committed relationship with wither LI. As she would have to give up her career, as a seducteress.
The ending scene where Lillian rejects Emile, WAS SO SADDD. Like this man literally just accepted his loss and went on about his life, and he was so hopeful.
Also I noticed that u have released a game, I'm currently downloading it and overall it seems to be right down my lane. Good luck with ur development btw.
