A boy called me a young man.

Definitely a nickname. And the relationship couldn't be better. Just use this. This is not only limited to boyfriends and girlfriends, but also my baby daughter Nizi. The usual friendly address is "Little Nell".

Of course, on some occasions, the word may be derogatory, but it can be heard at once.

Ps: I'll just call my girlfriend Xiao. Even in public, it's not too ambiguous, but everyone can hear the romance. Otherwise, you won't be ashamed to die if you are called "dear" in public! ! Haha, happy girl.
