The game's rocking as ever. Got a dumb question, but as someone who tends to play "chaotic" characters, picking hot situations in the spur of the moment - does getting into a relationship with any of the high school colleagues block other characters' arcs? I know there are some cool cameos between certain arcs, like Dimka helping you get rid of Niko (or is it the other way around) and then Sonya or Fedor helping you get rid of the blackmail altogether. But does being in a "sort of relationship" with Igor prevent you from progressing with Katja, Lariska, Fedor, Artem? Or are these arcs mostly "blind" to each other and leave you free to roleplay?
I think Fedor does break up if you cheat, and that it blocks further content with him. Is it possible to accept his proposal, advance as far as there's interesting content to be had, and then "break his heart", like a proper slut?

Does that make him hostile to you, or just indifferent? Honestly, I don't have any particular interest in breaking hearts as Sveta, if it were possible to convince them to accept an open relationship. After all, she is a succubus, even if/while she doesn't know it. She needs to perv out.
Would love a few hints on which blocks to expect, so one can combine these arcs and have as filled and varied an experience as possible throughout both high school and uni. Thanks!
