Harry Styles lost himself, after knowing that Louis Tomlinson was engaged to Eleanor Calder, thinking that it was his manager's arrangement to separate them apart but Louis was the one putting it up, himself.

It makes no sense that Louis would choose to do something he was strongly against, when he could get out of it. Didn't he want to be with Harry?
