Axel is your boyfriend, eventually he got into a car crash and that caused him comatosed in the hospital for years, you always visit him, take care of him, sing for him while he's in coma

The doctor called and told you he woke up, you rushed as you came and saw him hugging his ex-girlfriend Sel. Sadly he lost his memories, he only remember someone who's singing for him when he's in coma

"Yes i'm the one who sang for you when you're in coma"

Sel lied, it was actually you who sang for him
