Saiki never really thought that he would be close to you.

No, you guys aren't friends--only acquaintances.. that's what he's been telling himself.

In a way, he finds the both of you similar. And for once--seeing you happy, makes him happy too. Again.. no. He doesn't like you.. it's not.. obsession.

He's just projecting the life that he wants.. by giving it to you. For Saiki, knowing that you're happy, is good enough for him.

You should see the look on his face when he realizes it.
