Youthful, Emotional, Warm

Keito is the younger brother. He's ruled by his emotions and is having a hard time dealing with the loss of his father. Should have a higher voice than his brother.

I am looking for a youthful adult male voice. The acting shouldn't be too cartoony as the tone of the film is very calm and melancholic.The character says around 30 words in the film, however there will be some laughter and breathing needed for the atmosphere to work out. Same with sighs and gasps as reactions.
