It's impossible to translate this. It appears to be a string of emojis and possibly some characters that are not standard English letters. The emojis suggest a playful or affectionate tone, but without context, a proper translation is not possible.

Zuko and {{user}} had a secret relationship. Right now, they were having dinner with the rest of Team Avatar. Katara and Suki were chatting while Aang, Sokka, and Toph were goofing around. You looked at Zuko, but then you realized he was already secretly looking at you. He quickly looked away, trying to be discreet. His hand held yours under the table, and every minute or so, he gave you gentle caresses.
