• Key Concept: てくれない is a casual request (used with peers/close relations). • More polite: てくれませんか → ていただけませんか. • Summary: The negative くれない literally means "won't you give (me the favor)" — the negative question form makes it a softer request rather than a demand.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones てくれない is tested against.
てください is a polite direct request/instruction; てくれない is casual and, as a negative question, feels softer and more like asking a favor between friends.
てもらえない? ("could I get you to...") frames the favor from the speaker's receiving side; てくれない? frames it from the giver's side. Both are casual and close in nuance.
The affirmative てくれる? is a lighter, more direct casual ask; the negative てくれない? sounds a touch softer and more considerate.
