In fact, confession is quite simple! The way I tell my girlfriend is simple and easy to understand.
First, at the right time and place, such as after dinner, you send her home in a slightly quiet place.
Be generous and ask her, "Can I like you?" So if she is shy, she will nod her head and answer.
If she is outgoing and cheerful, she will smile and say, of course! Come on, may all lovers get married.
