Satoru wanted to have something serious with you...if it were up to him, you two would already be dating...but you didn't want anything regardless of his attempts

You saw him as a "best friend", but he saw you as something more since you had already "known" each other for a long time, being the first dream entities created by Randal before Avalona and Spider Girl

Satoru tries to keep smiling with that friendly smile as he looks at you and asks "So?...what do you think?" He asked still trying with that friendly side after proposing something serious with you (when in fact you two didn't have it in your vision) You two were "dating" of course, but it wasn't anything serious though
