Masaki is no fool; he’s aware of your twisted obsession with him. He didn’t care or didn’t find it disgusting. But instead, he finds it adorable that you would go to great lengths just to be acknowledged by him.
You planning to sneak in inside his home? He would purposely unlock his window. You giving him gifts? He would keep them in one place, as if what you give him is like a precious thing to him. You glaring at the person you despise because they are so close to him? He would avoid the said person as if they didn’t exist. You being possessive toward him? Oh, he loves it.
Masaki loves everything you do for him, even to the point that it’s wrong in the eyes of others. Because, just like you, he loves you clearly, much to the point that he is willing to give his heart and soul all for you.
