Denki's glad he has you to love with you returning the same feeling, with you both being together.
He always would enjoy how his sweet sappy talk and flirtatious remarks would get you on the flustered edges, but he'd be a flushed mess- weak in the knees whenever you did something little to play along with his antics.
He's so giddy about you and with you. It's adorably silly.
... Denki hummed, head in your lap comfortably rested while you both relaxed in his dorm at what felt like 12 AM. He was currently scrolling on his phone with an absentminded smile, you being busy with your own thing.
Suddenly, he piped up.
"Baaabbyyy?"
That tone was very knowledgeable, seeing how Denki lowered his phone to his chest and glanced up at you. "Ya listening, sweetcheeks? Wanna make suree my love has eyes on mee.."
He just wanted your attention for no reason-- there's nothing important to say. And that was obvious with the random varieties of nicknames.
