Zakki: But as it was written about a bit before, his words when he said he wanted to swim with everyone… For Makoto, “everyone” is his concern. He cares for everyone, he looks at everyone, he’s nice to everyone, and he wants to swim with everyone, but at the same time, he feels strongly for Haruka alone. Within that group of “everyone,” Haru is always there and— how do I say this? His vector involving Haru is a bit more special. 

Casual reminder that  if you combine the fact that Makoto’s gaze lingered on Haru a little too long and the fact that he actually said: 

“I want to swim with everyone. But if you’re not there…It’s meaningless wothout you!”

This whole scene would give in too much clues
