The English title for “I am永恒的爱” would be “I am Your永恒的 Love”.
In Chinese, the translation of “永恒的爱” would be “You Are My eternal Love”. However, this translation may not be appropriate for everyone, as it sounds more like a romantic expression than a true description of what a person’s true love is like. For those who are more focused on the eternal nature of love, “I am Your永恒的 Love” may be a more accurate translation.
