Correction/Other method/FYI

6. I Hate People
Finish the day without helping any people.

• Don't complete any tasks on that playthrough.
  
• Except Cat task since it is tutorial.

Correction/Other method/FYI

1. You can still get "I Hate People" even if you help the Rabbit cheat (probably because it's a bad task) - by 脳怖
   
2. I'm pretty sure I did also help the frog on my bad karma run (feeding the spider to the frog), but I still got "I Hate People" achievement. Maybe the requirement is to not help only human beings?
   This theory is also supported by the fact that another achievement ("Complete tasks for all creatures and people") explicitly states both humans and creatures. - by RetardesPrime

-----------------------------------------------------------
7. A Long Walk
Finish the game with the most minimal number of Fast Travels.

• Don't use fast travel on this playthrough on your owns.
  
• Except one time. when you already asked Kenji for help and done retrieved red shoe near bench. You have to activate fast travel to Wisteria tree by your own.

Correction/Other method/FYI

1. You cannot get Lie, Cheat and Steal or A Helpful Soul WITH A Long Walk on the same playthrough because you have to fast travel to pick up the Tortoise - by 脳怖

-----------------------------------------------------------
8. I'm Not Ready [Hidden]
Refuse Kenji's kiss.
*PS. If you refuse Kenji's kiss. the checklist will left "Feel love from Kenji" unchecked.

1. On secret hideout tell Kenji you need Kiss as reward.
   
2. Lose the game against him.
   
3. Choose option "I'm Not Ready".

Correction/Other method/FYI

1. You cannot get I'm Not Ready on the Bad Karma route if you beat Kenji. you kiss him automatically so you can't refuse it. - by 脳怖
   
2. You can get I'm not Ready on the Bad Karma route if you loose to Kenji. He will tell you he should get something for winning and asks for a kiss. You then have the option to tell him you're not ready.
   I was on the Bad Karma route and just earned this achievement.- by Cheshie
   
3. If you choose to free the 2 girls but leave or poison Chie, you cannot get A Perfect Day or I'm Not Ready because Kenji will not be in the mood to kiss. - by 脳怖
   
4. i got 'better than the boys' and 'im not ready' achievements on the same play through... at the start of the interactive with kenji, i said i want a kiss if i win, then when i won, he asked me if i still want it, and i said im not ready! so you can get the achievements on the same play through, and you can refuse kiss whether you win or lose - by laurenestella
