Love y'all to the moon Shinsou×Denki×Monoma

DISCONTINUED

A poly ShinKamiMono fanfic inspired by Denki_Darling on Tiktok.

"Hey class 2A!" Monoma yelled, the only people giving him a short look were Denki and Shinsou, both had a massive crush on the blond and didn't even mind hiding it.
Denki and Shinsou had been in a relationship for about 3 months and were both poly, but never had the guts to ask Monoma to join them, mostly because of his outbursting personality.
"Don't ignore me you little brats!" Monoma yelled at them as they silently passed by. Denki couldn't help but redden slightly when Monoma approached him and Shinsou specifically.
What was he planning now?
