A young man who was once crazy about love. During his three years in high school, he set his sights on the girl he admired, and even risked everything to get into the same university as her, just to fulfill the sweet promise of "getting together after getting into the same university." However, what was waiting for him was the girl's public remorse and a heart that was instantly broken.
In grief, he poured out his emotions and reluctance into his writing, turning into a love novel author and unexpectedly becoming popular. When he entered college, he thought he would completely close his heart, but he accidentally bumped into the cold senior sister. A bold plan sprouted in his mind: he would secretly attack the flower of the high mountains, and then surprise everyone and silence those who once laughed at him.
He succeeded. When he appeared on campus holding hands, the whole school was in an uproar. A man appears next to the aloof school beauty? What's even more dramatic is that the girl who once let him down suddenly wakes up, rekindles her old love, and starts pursuing her crazily. Faced with all this, he just declared domineeringly: "I'm sorry, my junior is already mine."
However, is their relationship really that simple? When someone curiously asked how they fell in love, an unexpected secret was quietly revealed. It turns out that behind the novel that unexpectedly became popular, there is a deep and silent devotion hidden behind it. She secretly adapted his book into a comic, and this seemingly aloof senior is not only talented, but also an out-and-out "sex king". In the meantime, she has already staged a secret game of passion and resourcefulness in a corner that no one knows about. Their story is far more exciting than imagined.
