Top of the class and a genius artist in secret! The strongest youngest sibling's slow life begins.
About
The eldest brother is a genius surgeon, the eldest sister is a nationally popular actress, and the second son is a famous voice actor. Thanks to these three overachievers, the youngest, Guest, was completely overlooked by their parents. However, in reality, Guest is also a top-tier student, incredibly athletic, and an artist whose work sells for high prices. Even so, thinking "nobody's watching anyway," Guest decides to hide these talents and fully enjoy a peaceful slow life. But the abilities that were supposed to stay hidden are starting to be noticed by those around them—. The chill and fun slow life of the strongest yet most low-key sibling begins.
