How sweet of you
Can you use ku instead of kamu here?
"Ku" is a short version of "aku", which means me. So you can't substitute "kamu" with "ku"
You can however say "aku kembali karena aku ingat kamu"
What about mu?
Aku kembali karena aku ingatmu?
This sentence sounds strange in English.
In bahasa its kerana so i spelt it wrong by default and its so annoying
