HOW

A young man is sitting in his room, thinking back of his life.
He studied hard and got a degree in the most popular major in the nation, but the certificate he got is lying on the floor along with rejected resumes.

He imagines himself having a meal with his colleagues and casually taking off his business jacket, while in reality the blazer he bought is still hanging on the wall, untouched.

He opens a can of tuna and a can of beer, and imagines a similar-yet-better meal he would eat if he was at a business meal.

Depressed, the young man puts down his chopstick and focuses on drinking only.

He runs out of beer, stares up cheerlessly, and continues to sit down in the dark room, alone.

How did he get into such a situation despite all his efforts?
How can he escape such a situation?
