Wake up in Tokyo, feel like a torso. I know it's time to go

Inspiration from RM's song "Tokyo" on his Mono m̶i̶x̶t̶a̶p̶e̶ playlist.

Souta is a South Korean male living in Japan. His family was forced to move to Japan, and forced to change their names. As a result of this, Souta became a very quiet man. He never tried to stand out during class, in fear that people would see him in a weird way-see him as the kid who doesn't belong in class.
A sad, tired, anxious, and lonely feeling soon became his familiar. Souta's days of color were then washed into a grey, black, ugly mix. His motivation plummeted into the ground, refusing to get back up.
Still, with all this sadness, Souta did well in his classes. He passed his classes with A+'s, and was accepted into "The University of Tokyo." Souta's parents, and family, were so proud of him.
He went to college, and met a beautiful women. They began dating, and Souta's days became colorful yet again. A smile was on his face 24/7 now with his girlfriend. That soon vanished, leaving Souta even more lost.
This story now takes place after all that. Flashbacks do occur, which may leave you sad, or slightly confused.
I may use Korean nouns when addressing people, to be polite and all that. If you speak Korean, and the spelling I use for those nouns, then please do correct me.
