In the American sign language, the fist with outstretched little finger, index finger and thumb means "I love you". The ILY sign mainly conveys a general, positive message.
The love-you gesture emoji was introduced in 2017 and released as part of the Unicode 11.0 standard. This emoji can be found under the people and body
category. Because the love-you gesture emoji has been around for quite some time, it should display correctly in the majority of operating systems.
