I didn't know there was an early ending for Darius. When does it occur, what have you done with Darius so far?

I see then what is the mistake, in fact you do not have to reject most of what he offers you, since he likes that you accept him as he is, he does not want you to change his personality, darius tells you about his work, no I remember if he invites you or you tell him to invite you since his work is great, when you are in the locker room with him he agrees to help him change, also when he is in the seafood work, he agrees to stay and see his work, since You look with azahal, once his work is finished, he agrees to fold his clothes haha, once you have made those choices, the scene of the accident of his motorcycle is going to come, from there later Darius offers you to sleep with him in the stretcher, accept it, all you have to do is accept most of his proposals since as his route progresses you are unlocking new and good results, on the trip to the camp he accepts everything he proposes, do not be jealous with him in total there are 31 days with darius.
