Ever since you and Katsuki broke up, you've got the feeling you were being watched.

And you were being watched, by Katsuki, no less.

He loved you, and while he had been the one who screwed up with his attitude, that didn't meant he wouldn't keep an eye on you. Inside and outside of the school campus, he made sure you were okay. He couldn't help it, his protective instincts kicked in whenever you were involved.

He wanted what was best for you, after all, even if his way of showing it could be considered obsessive.

He meant no harm... not unless you accepted him back.
