This happened because his sister was wearing his jersey the day before, but Keisuke doesn't find the right timing to laugh it off. The one who helps him in this situation is his good-looking best friend Shinoda. Perferming perfectly in tune they get out, but when Shinoda watches Keisuke take off the pantyhose he suddenly changes...?
