Sakusa heard this news and was getting angered and almosting losing it all. Y/n has notice the effect on him. Y/n hoped it would fade so didn't bring it up. Y/n knew coukd trust sakusa right?
-------------------------------------------
One of those days sakusa got home knew he had to act. He couldn't hold back anymore. First he had to plan it all out. He wrote down everything. He had a whole planned planned out. Now he just had to wait antell the perfect moment when he could act. It was coming soon. Mostly,with how everyone was going to get interviewed. He had to act soon. And he was achually kinda thrilled how good his plan is..when he had got down with his thoughts threw his notebook in a safe he had. He couldn't let anyone. Find out. He was going crazy but. He was smart with observing. He knew the ways people couldn't suspect to much and find out his secrets.In his safe was a notebook filled with everything about Y/n. There was pictures he catched without you noticing. He just observe and leave out a tiny chuckle knowing you were going to be all his very soon. You couldn't do anything about it. He was very clever. He knew you'd be scared of the plan at first once he gets you started with it. He had to make you as comfty as possible. He went to sleep that night filled with all those thoughts of his plans.
