'ki' is the Chinese character that means 'to shine'

"They're doing the same thing most of the time."

"They are 'Taiki' and 'Tomoki',
and 'ki' is the Chinese character that means 'to shine'.
I'd wanted to use the character for their names."

"Because they're twins, many people say to them 'Twins! Cute!'.

Sometimes I hear harsh words, but they are called cute many times, so I appreciate that."
