After that incident, Yujin got demoted to the second string and will not return to the first string until she improves

not only in her sports field but also in her academic field.

developed a phobia for balls.Now in a bind, she is on the verge of getting demoted too and will not be able to participate in

any games outside of school premises.

Now in a tough position, both students suddenly cross paths and decided to help each other out on their problems.
