Why would you go Chick with Nicole? Their journey of love began with him balls deep in her sphincter in the Pink Rose, and only a "Huge DIK" can pull that off.
I'm pretty sure that if you choose all DIK choices but don't fight anyone, you'll be neutral. Not 100% sure...
EDIT: Just did some research (looked up one of my old posts):
A neutral path that kinda makes sense (green is choosing the Chick option, red is choosing the DIK option):
- Fight Troy or storm out
- Accept or reject Quinn's offer
- Leave Steve or Talk to him
- Fight Jocks or run off
- Progress things with Jade or stop her
- Party without limits at Strip club or don't
- Smoke Weed with Quinn or don't
- Fight Caleb or Walk away
- Punch Tybalt or Walk away
- Fight Tommy or don't fight
- Use Fake ID or Stay Home
- Go to Strip club or volunteer for Old folks home
- Evict the Alphas from the HOTs party or ignore them
- Study the answers in toilet or flush them (or just walk away)
- Get revenge on the nerds or calm Derek down
This would be the "Lover not a Fighter" path.
