My Youth Has a Serious Knight Disease

I like to secretly tilt the umbrella towards the other person when holding an umbrella for someone else, I like to secretly point the knife tip at myself when passing scissors to others, I like to pretend not to notice when the desk mate leans down to pick up a pen to protect the corner of the desk, and I also like to find a way out for her when others are embarrassed. Or I will主动和一些不爱和别人说话的内向同学搭话
But actually, I am just pretending to be tough.
