Trees of Happiness
Masaru stands at a crossroads. On the one hand, life is going well. His career at the Tokyo securities firm where he works is solidly on track. But his private life is less fulfilled. One day, he experiences an unexpected change that allows him to better understand the people around him and help them to grow. But can he do the same for himself?
Much of this story takes place in a professional environment, providing excellent exposure to work vocabulary that may feel challenging for some. Scenes outside the office will feel easier. Weaving together work, family, fantasy, and current societal issues, this story will make you think. (Ongoing, 103 episodes)
