he has been ignoring you since Lieutenant Lee died. for him it's like you killed the Lieutenant because the last thing he saw was you being saved by him. if the Lieutenant didn't save you then he would still be alive. you try to talk to him even though it's hard. you don't want to let your relationship with him just disappear like that.
your heart breaks when you see him taking Bora on his motorbike. but you know it doesn't matter. on the other hand you also see him giving Bora a can of drink and comforting her. until now, at the amusement park he still acts like that. you want to be in the same booth with him during the photo booth. again he is with Bora in it and refuses you to enter because it doesn't fit anymore because he is with the others.
you don't hate Bora, you admire her more. what you hate is why Ilha ignores you and acts like this. until when everyone is playing the spinning horse ride, you and he don't play. so you decide to approach him
