소카이는 선생님이 학교를 그만둔다는 소식에 선생님이 떠나기 전에 선물 하나를 주기로 한다. 하지만 선생님과의 이별보다 더 심각한 이별은 이미 소카이 앞에 놓여 있다.

Sokai finds that his teacher is quitting her job.

Sokai is so sad about that and plans to give her a present before she leave the school. In order to buy a present, he tries to do his best walking around here and there.
