How to Say ‘You've been running through my mind all day.’ in Japanese
一日中、僕の頭の中を走ってたから。
ichinichijuu boku no atama no naka o hashitsu te ta kara
[ee-chee-nee-chee-JOO boh-koo noh ah-tah-mah noh naka oh hah-SHEET teh tah kara]
🇯🇵 In Japan: This is the answer to 疲れてない? and is translated straight from the English joke. Japanese listeners will likely find it charmingly corny rather than smooth, so deliver it with a grin.
