In the end, when he arrived at the school after school, that customer also was in the store. The store manager hung a sign that said "we are closed today" . When the teacher enters the store, he sees the sign and realizes that the store manager and the teacher know each other. The teacher promises to return all of the money that the customer has paid for the cafe. He tells the students that the situation is not as they think. He says that it looks like the teacher broke up with his sister because he was planning to travel abroad. The students ask why they are still at the door, but the teacher says that they are just passing by. He then tells them that he cannot explain the situation to them, but that he will talk to them later. He promises to treat the students to some desserts and then he will help them make coffee. He also tells the student that he is worried about the teacher-sister relationship, but says that he and the girl have known each other for about two years. The two of them have been playing a game called "yakone dreamland" , and when the teacher comes across a wounded sniper, he asks the girl to accept the mission.
