Isnt Take pushing Umeko and Macchan together? IDK like, he knows that he himself isn't that healthy and the crushed feelings of being away for so long will feel like temporary disparation. Now I know why Take is that harsh with Umeko. He felt that she once discarded him away (it's totally okay for Umeko to do so anyway, since her life is not all about taking care of sick friend. She too has life to do). But yeah, I think Take needs other friend than Macchan and Umeko to fresh his own distorted view he cultivated all these years
