The Missing 19 Years

Yu Tianying and Chang Yan had been childhood sweethearts ever since they were in diapers. They were like a big sister and big brother who had sworn brotherhood. But then something changed when they started elementary school. Normally, a romance broken up by being placed in different classes would happen when moving up to middle school, but this twist directly replaced the male lead. Ah, the heart that couldn't refuse a generous offer fell for another boy instead. When Yu Tianying finally realized what was going on, he decided to secretly set the plot right. How could a youthful, ambiguous crush stand against his scheming? The domineering male lead and the naive male lead started tearing into each other. As expected, the shameless one beat the one who still had some self-respect. The two kept trading places as each other's first love. A scumbag man and a scumbag woman? Somehow, that doesn't seem quite right. With a twisted devotion, Yu Tianying managed to claim the male lead's place. After a long and miserable psychological journey, just as the old witch made her entrance, fate itself helped put Tianying down for good...
