緒 together

SEE HER OCELOTS play together.

The professional rappers Wu-Tang Clan wrote a string of hits together.

together ★★★★★
一 (one) + 緒 (together) = 一緒 (together)

confidential ★★★☆☆ KIDS
内 (the inside) + 緒 (together) = 内緒 (confidential)

usually defined as 'confidential,' but that makes it sound more serious than it is - like a spy document or something. Actually, 内緒 is kind of a kids' word. "Keep this information between us two."
