Sooo about Daiki :
Sawato was in love with Daiki, Daiki had an accident and lost his memory, he became completely different.

Sawato felt betrayed (?) so now he's blaming (the new) Daiki. He wants the new Daiki to give him back the old Daiki (even though it's not Daiki's fault).

For Sawato the Daiki before and after the accident are different people.
He loves the old one, who was quit cold and hate the new nice/loving/funny one.
(sorry it's a mess hahaha)

Ah.. I see. Thanks for the info.
