Why Are My System Tasks so Difficult?

In the cold winter of my junior year, I was emotionally frustrated and dumped and got the system. The first task of the system actually asked me to pursue the school beauty? The school beauty is actually a sea king? Do I need to win her heart within a week? Every time you complete a task, the system will give you generous rewards. Money, ability, knowledge. It seems that my cold winter is finally coming to an end!
