It's easy actually when you are in game just press f12 on your keyboard, click on the storage bar, look for cookie there should be dsp website inside the cookie, click it. It pretty much have all the information, just remember some of the information are not fully loaded until it meet requirements, so just make sure keep scrolling down on that tab, you can change it, the only downside that you can't unlock pay stuff (at least I don't know how), you can get the achievement for it but not the scene.
If people are struggling to get score/rel point on certain person just cheat. Unless this game have back system, it will be a headache and not worth the time just to get that scene.
