A strength of Japan is how well they make slice of life dramas and this show proves this very fact. The show follows a 5 year old Kotaro who has begun living on his own due to mysterious circumstances, impacting the people around him in positive aspects. The child-actor does a fabulous job of acting as a child too mature for his age and splendidly delivers the character's complexity because although his mannerisms make us forget that he is a child, he shows glimpses oh his childish innocence right when it is needed, which is so fascinating! The plot is simple but teaches us life lessons as we see glimpses into the lives of the adult characters that Kotaro encounters, each with their own set of problems and past scars. Seeing all of them grow together with Kotaro really teaches us audience how we never stop learning/progressing in life, and how much we can learn from children as well. Definitely recommend this drama for its simplistically beautiful plot which is delivered wonderfully by the multi-layered characters. BONUS: the child playing Kotaro is sure to charm everyone with his cuteness UwU
