Gokusen [ごくせん] Funny and Enjoyable [Rating: 10/10] I like this drama... It is so funny and enjoyable especially Yankumi. She try hard to be 3D teacher though she did not look like a teacher... Well, What I want to say is that this drama is worth of watching. Anyway, I am curious Yankumi will choose who to be his lover. At the end of the series, you can see that there are 4 people like her. One of them are Sawada Shin. Haha... Maybe only Yankumi know.
