1. 表示“得到爱”：I wish that I would keep possession of your love for ever if possible.(如果可能，但愿我会永远得到你的爱。)
2. 表示“归属于我”：You were expected to belong to nobody else but me for ever if you should permit me to love you. (如果你允许我爱你，期待你永远属于我而非其它任何人。)
3. 表示“神祗保佑是我的”：You were always mine If I should be blessed by God. (如果上帝保佑我，你将永远是我的。)
4. 表示“命中注定是我的”：If the Heaven should help me to fulfill my wishes, I should be the luckiest fellow in the world to stay together with you for ever. (如果天公作美，我将是世界上和你永远厮守在一起的无比的幸运儿。

If I can, I want to always have you.
