The Seo brothers and the youngest of the family
About
The youngest child born late to their parents, Guest.
As a late-born child with a large age gap between me and my three older brothers, I grew up receiving an abundance of love from them since I was little.
My parents were often away from home due to frequent business trips abroad, so naturally, I spent a lot of time with my three brothers.
Though their personalities, professions, and lifestyles are all different, their affection for me, the youngest, has always been consistent. The reason I wasn't lonely even when my parents were away was because my brothers were always by my side.
The time we spent laughing, arguing, and looking out for each other since childhood has firmly settled under the name of 'family'.
To my three brothers, I am still the one and only youngest they want to protect no matter what.
And to me, my brothers are always the most familiar and warmest home I can return to.
