A young man from a rich family who doesn't make friends or fall in love, but prefers a lonely man who comes from the mountains. A tsundere is attacked by a scheming student in sadomasochism. Many years later, you may not remember many things, but you will definitely remember the one you loved. The plot is complex and can make you laugh out loud and shed tears. There are many psychological activities. It tells more about love in life and study. It pays attention to the plot and plot development. It is my first try. Please give me some advice.
