Shishi was tired of all the shits.
He literally was.
Everyday doing the same things - taking morning classes, returning home, fapping, eating, sleeping and running errands.
He wanted something new.
So, he with the motivation to change his life started to perform shadow fighting in his courtyard.
After a while
He felt pain in his head
He then tried very hard to focus and push his limits.
But he couldn't, he was consumed by the imaginary scenaries in his head.
