Days: Playing Soccer with You is Super Fun, You Idiot

SINOPSIS

It’s the first day of the joint training camp. During dinner, Tsukushi overhears the students from other schools talk about Kazama's middle school days. Curious about what happened in the past; Tsukushi tries his best to ask his roommate, but can't quite do it. When Tsukushi wakes up the next morning, Kazama's missing; apparently he went to train by himself on the pitch.
