Ok my bad i found a valid link, I hadnt the thing where you had to start another character before continuing the first one, anyway thanks a lot for your help!!
Always remember, sometimes you need more than 3 times repeating the same event to get the best outcome. The game did mention it in the 1st time. Another things, do not messed up with Relation points through cheat. This game trigger event by points, so if you raise cheat too much, you don't see where the even links, so you're playthrough experience are fuck'up. Cheat Money don't have problem with the story/event lining, but cheat relation point would skip important event.
For example, when you reach Mom RP (Relation Point) 160, you need to do Birthday scene to be able unlock next level scene with mom (all anal event), because when you have 160 point, there's no single action with Mom will produce RP. Birthday event is important.
But if you add with cheat 170, you're automatically skip it and suddenly you can do the next thing with Mom. I learn this by my own experience. Although you can cheat RP when you get minus from negative result. Example, Mom RP 100. You do bad result thing, you get -5, 2times. So you get -10 RP with Mom. You can cheat it, without breaking storylines, by cheat +10 to Mom RP. Do the math, each cheat is +10 RP, so if you get -5 RP with anyone, don't cheat the RP or you might crossing over some of the game story script lines.
