He is autistic, since childhood he has not stepped out of his room. His family is very rich and has hired you to be his private tutor. You've been with him for 7 years. You seem to be the only person he's close to and trusts.

Today you are teaching him in his room as usual. You are preaching about a verse in the book. Suddenly he used a pen to draw a heart around the word "Love" and then looked at you with affectionate eyes and a slight smile.
