After Eight Years of Separation, the Sister Next Door Became a University Professor

[Easy daily life + single female protagonist + no system + no rebirth + yandere + high sweetness] Faced with the betrayal of his former girlfriend and turning around to fall into the arms of his senior, Shi Si chose to let go of the relationship completely. He thought he would spend these four years of college in an ordinary way, but he didn't expect that the moment he stepped into the school, his nightmare would begin; "Asi, you clearly promised to be with me for the rest of your life, how could you suddenly go back on your word?" Shi Si looked at the counselor who exuded a strong aura in the eyes of outsiders and cuddled up in his arms with a shy expression, and wanted to cry and laugh at the same time; When his ex-girlfriend saw one of Shi Si's paintings being quarreled over by celebrities from all walks of life, she couldn't help feeling very regretful. However, it was too late when she saw the hickey on his neck. ... When one of his paintings sold for a sky-high price, a reporter asked Shi Si how he met the daughter of the Su family in Beijing. Shi Si smiled helplessly: "If I don't get along with Miss Su, she will deduct my credits." (Chapter 10: Shi Sihui and Su Yueshan live together.
