A group of college students who just came out of the ivory tower, time flies, and they accidentally enter the season of marriage and love. Under the organization of the major university alliances, among the alumni groups, and on Penguin, the leftover men and women in the city finally shed their previously reserved faces when they struggled to get what they wanted. When love and sex were fully exposed, everything began to change quietly. As a pseudo-alumni, Shui Ruohan entered a colorful world, and women opened another door for him. She felt that she was beginning to become sexual and transparent. When passion was ignited, he discovered that love is actually very simple. It needs to be straightforward, abrupt, unscrupulous, and a bit rogue.
