The story shows two different back story that depicts peoples current life / work. One who struggles due to his low self esteem and one who experienced loss of loved ones. The show showed how exhausting life can be that you'll eventually agree due to to frustration and exhaustion. One scene that caught me off guard was when Hiro said the reason why he is reluctant in leaving and made me feel sympathy with him. Lot of people choose to do something they're comfortable that makes them reluctant to change and be contented with what is with them right. However, it shows how brave the MC is for doing it. Kudos to all the staffs who produce this good show.
