A story of brothers growing together. This is a story about the life of brothers whose day is always eventful from the perspective of the older brother. To the older, a 
younger brother is someone he knows so well, but also can’t understand at all. That guy is so weird, fussy, irritating, and does whatever he wants! The older brother 
always says things like because he’s my younger brother, and if he wasn’t my younger brother... But at the same time, the brothers make their own memories and 
secrets to interact emotionally, and they gain greater understanding about each other.
