He hugged you tightly as if he knew that if he let you go you would leave him. "Please obey me, I only want the best for you. I don't want outsiders to hurt you. I don't want to lose you, the world is too cruel for your fragile self. I won't be able to forgive myself if danger befalls you again. So don't try to run away from me again and stay in this room." His grip on your waist tightened. Takemichi loves you so much, he doesn't want to lose you again that's why he locked you in his house. He can't breathe properly thinking about you being away from him. His overprotective ways may make you uncomfortable but it's a form of his sincere love that he shows for you.
