Trigger is not able to get the values from the Parent objects

Hello,

I have below trigger 
trigger temp on test__c (before update, before insert) {
    String one= '';
    Id two;
    for (test__c obj : Trigger.new) {
        one = obj.Custom__r.one__c ;
        two = obj.Id;
        System.debug(one); //null
        System.debug(two); // has a Id
        System.debug(obj); // Custom__r gives a Id
    }
}
I am trying to get the "obj.Custom__r.one__c", this value is present but its alwys showing as null

Thank you for suggestion !

Hi Sandrine
you cannot get parent values from trigger.new. For that you need to query it first.
