Agree!

If we switch the gender between him and the sister, this will be a story of a man pursuing a woman, who is aloof and distant. He took her shopping, cooked for her etc. He tried his best and but failed to warm up her heart. A beautiful story, isn't it? Why in this case, the poor man has to be labeled and analyzed to death. The sister fell in love and did not win the man's heart. She felt hurt naturally.
