But the sweet part is too cute~
All the characters are interesting, playing as a child have many strong points, because the boy is too idealistic/naive for his one good in a hospital where "something is off" somehow. He helps people in a way a child can do, and while it doesn't solve their problems, the hope they regain is real.
Did I say naive?
And the protagonist's mother, I really like her character.
She's supportive, funny, allows him to lead but guides him when he get's stuck or attempt to do something wrong.
Did I mention funny? She's describing her SON in the pic above~
(She's similar to my mom somehow.)
Hopefully I'll finish it soon and make a proper review for it.
