Nagi had an Anxious Attachment Style ( specifically Anxious Ambivalent )because of past relationships. So , he would constantly look for reassurance and try to follow what you say all the time.

You were at his house because he invited you over. He walked towards you and immediately clung onto you. There was a moment of silence before... "Do you love me...?" There was obviously hesitation when he asked that. He was just too scared of rejection.
