May 20, colloquially known as '520', is widely celebrated in China as a day of love. Borrowing its significance from the numerical representation of 'I Love You' in Mandarin, '520' has become an informal Valentine's Day particularly cherished by the younger generations and couples. On this special day, many idols extend warm wishes to their fans, urging them to partake in the celebrations. Among the idols who extended warm wishes included Jessica Jung.

On May 19, she landed at Shanghai airport from Seoul with a surprise for her fans. She had brought chocolate from Korea to give to the fans at the airport to honor 520. Her fans appreciated Jessica's sweet gesture and sincerity.

Fans were happy to receive chocolates from her and were touched to receive them from her personally. They even posted on Weibo with the treats. Jealousy was expressed by the fans who were not present as they wished that they had also received chocolates from Jessica.

Jessica later made a post on Weibo which garnered a lot of attention. Jessica perfectly embodied the day's romantic mood with her pink outfit and heart-shaped balloons. Fans praised her sweet visuals and complimented her pretty outfit.

She also gained a lot of attention for the handwritten letter she posted. 

"My dearest maomaos.
I always receive letters from everyone, so on 520, I'm sending everyone a reply.
Time FLIES~ don't you think?
It's summer again.
I know everything you all are anticipating for!!!
Wait for me a bit more.
They're on the way.
Thank you~Love you~."

In the letter, fans believe she is teasing her comeback and asking fans to be patient as it is coming soon. Fans are eagerly waiting for her album release, as Jessica has recently said that she plans to make a comeback and release an album in late summer.

Jessica's Chinese fans had also prepared a surprise for her. One of her Chinese fansites, MrGuard_J-护猫警长, had planned and prepared a drone show for her with 300 drones. Jessica had seen the event and shared it expressing her love for her fans.
