Harry's just always there for Louis, and sometimes Louis notices how his shoulders slump, how his body grows into a dejected and hurt position, whenever Louis moves away from Harry's touches. It makes him feel bad. The whole situation really makes Louis pity the boy who desires him so much, but never will get him in that way he so desperately wants. It makes Louis keep delaying telling Harry things he knows the younger boy won't like. And maybe that's why Harry's the last one to be told about Louis' and Eleanor's engagement.
