Okay, I missed this error 

ERRORS:
testmodels.RelatedModel.main: (fields.E303) Reverse query name for 'RelatedModel.main' clashes with field name 'MainModel.relatedmodel'.
	HINT: Rename field 'MainModel.relatedmodel', or add/change a related_name argument to the definition for field 'RelatedModel.main'.

And I still have this questions:

  1. Why does it clash?
  2. Why related model have two names: 'relatedmodel' and 'relatedmodel_set' if we can use only second one?
  3. Why name property can't return 'relatedmodel_set' to avoid stuff above?
