The MC has skills when entering the 'prison of lust'. Basicly when you activated the skill, it will increase the duration of sex from the MC (So, it's like you will get two sex scenes when having sex with the female character), If the skill is not activated, then you will only see the first sex scene. I also use this skill to increase the character interest of the MC.
In this game there is no forced content, the MC must approach them nicely (just like a hangout?) and then seek information from them. If you mean romantic scenes or sex scenes, you can avoid them, depending on how you respond to the route in each scene.
Thanks :))
