In that midsummer, Lin Min, a young college student in City S who was about to enter his sophomore year, fell out of love! A well-planned plan to follow his ex-girlfriend on a date failed miserably. Not only did he lose his face, he also drank and spilled the cappuccino of a great guy next door. Unexpectedly, in the subsequent programming training, Lin Min and the great god met again, and accidentally became the great god's roommate. In the hard training life, he faced several important problems: the declaration of war by his love rival, the troubles of his ex-girlfriend, and the heavy pressure of study. But the top problem was: how to survive in front of a nearly paralyzed master with severe mysophobia! However, as time passed, Lin Min was surprised to find that the "her" in his heart had long been replaced by "him"...
