When they first met, he thought the other was a human trafficker trying to kidnap his little sister. Later, he learned that he was the one who ranked first, and started paying attention to him. Each exception he made also caught the other's eye. Their meeting in the library was deliberately arranged by him. At the New Year's Eve party, his guitar and the other's suona turned out to be an unexpectedly perfect match. That also drew someone's attention to their "duo." Before he knew it, he couldn't live without him.
The time he was away for over a month was during winter break, and that winter was bitterly cold. When he finally returned, he brought her a "little sister." After that, he couldn't concentrate on his exams, and his grades gradually slipped. Two months before the college entrance exams, he finally discovered the truth about that so-called "little sister." He made a bouquet of lollipops by hand, because the other loved sweets, and forgave him. As the final push began, the former first- and second-place students returned to the top.
After the college entrance exams, he personally sent that "little sister" to a psychiatric hospital, then forgot she had ever existed.
They filled out exactly the same college applications, happened to get accepted by the same university, and happened to be assigned to the same dorm room. As it happened, their two roommates were out all night every day. It was all just one coincidence after another.
From meeting, to getting acquainted, to understanding one another, and then falling in love, their ending had been destined from the very beginning. They were meant to stay together. The DR he gave him was engraved with LY.
