YOU SAID:
I am in love with nine people, and none of them know I exist
INTO JAPANESE
私は9人に恋をしていて、誰も私が存在することを知らない
BACK INTO ENGLISH
I'm in love with nine people and nobody knows I exist
INTO JAPANESE
私は9人と恋に落ちているし、誰も私が存在していることを知らない
BACK INTO ENGLISH
I'm in love with nine people and nobody knows I exist
That didn't even make that much sense in English.
