These specific path variants simply show how many playthroughs are possible.You guys pointed out to me that you can skip fucking Axel in chapter 11 (thus Jeremy won't tell Ian that Lena cheats), and I recently put in in practice. You want a run of that?
Again, you can max Axels relationship and fuck him in chapter 9, then pick the bottom options and don't masturbate relax, Lena can refuse him in chapter 11 and in chapter 12 she can visit him before the trip and fuck him.
Ian is blissfully naive, but the script remarks how tired and uninterested Lena is during the sex with him (because she is sore from Axel).
I consider this the equivalent of kissing, but not fucking Cindy in chapter 9 and Lena being unaware that Ian cheats on her.
I have currently nine paths I play and save for.
Ian/Alison (full romance), Ian/Alison (full romance with threesome fun), Ian/Alison (romance/fuckbuddies, but also dating others),
Ian/shy Holly (full romance), Ian/encouraged Holly (full romance, with a trinity save variant too), Ian/wild Holly (full romance if now possible)
Ian/Lena (full romance), Ian/Lena (romance/open relationship, both some dating with others), Ian/Lena/Holly (trinity)
I generally couple up Emma/Perry (also gives boni for helping him), if my Ian is not with Lena or in an open relationship, she is with Seymour and/or Axel. I never pursue Emma and Cindy as Ian, never Jack as Lena. Normally Jess is with Dave (as it should be!).
