Yes, all along, he had no interest in women. Those women, either pretentious and willful or affected and artificial, just looking at them made him feel sick, let alone anything else.
So, all these years, there was only Zhou Yalin by his side.
However, he never laid a hand on Zhou Yalin.
They had been dating for years, the most they did was hugging, and that was when Zhou Yalin took advantage of his distraction to suddenly embrace him. That hug lasted only three seconds before he pushed her away, for which Zhou Yalin was upset with him for a long time.
In modern society, couples who have been dating for years and still maintain such a pure relationship is indeed... a bit abnormal.
To say he never felt an impulse towards Zhou Yalin would be a lie.
During the time he was blind, when he realized his feelings for Zhou Yalin, he always had an uncontrollable urge to be close to her, which is a man's instinct towards the woman he loves.
