You have my love. The box in a heart shape with a ribbon could contain chocolates or jewelry. Popular on Valentine's Day or on birthdays. Or someone gives you his heart.
The heart with ribbon emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the smileys and emotions
category. Because the heart with ribbon emoji has been around for quite some time, it should display correctly in the majority of operating systems.
