The Pruning of a Sakura Tree

What if, during the rooftop fight between Umemiya and Takiishi, Umemiya hadn't won? What if Sakura stepped in to protect his friend? What if Takiishi became obsessed with Sakura as a result?

A Takiishi x Sakura and Endo x Sakura story that I've had in my head for a while. Please don't mind how bad the writing is, it's very rushed and very cringe lol ;v;
