Just done reading Earthlings last night. Tbh I'm still feeling bad for Yuu. He didn't deserve it. I will be his friend.
Hopefully he will turn into strong man and can make decision. (You) will come to Yuu and then say if she's his friend. Getting close for each time that he can put wall between him and Natsuki (the promise between him and Natsuki won't occur) also he has to confront Mitsuko, his mother.
Yuu will turn into adult and like her. They will date afterwards. So sweettt. Yuu will come back as a couple with (you) then meeting Natsuki with her husband, but Yuu won't involved with their mindset. Happy ending with (you) insteadddd.
