Akama Miki is a cute, 12-year-old child model from Canada with close to 500,000 followers on her Weibo page (China's version of Twitter). The only person she follows is 24-year-old Chinese pop singer Zhang Muyi to whom she posts lovesick messages, such as: "Wait until I'm old enough to marry you, and then I'm going to say 'I do.' "

The everyday scribblings of a young girl with a crush? Think again. The message was written in response to Zhang Muyi's own post featuring a photo of Miki pinching him playfully on the cheek and the message: "Today we're super happy, laughing, being crazy, had a nap and practised singing. I said to Miki, 'I'm going to be with you as you grow, I'll always wait for you.' "

Akama Miki and Zhang Muyi post pictures of themselves together regularly for adoring fans.

Both of their accounts are filled with photos of the couple running on the beach, working in the studio, eating birthday cake and curled up next to each other on a sofa. They frequently declare their love for each other, with Zhang Muyi saying on Miki's recent 12th birthday, "I simply can't wait for these next four birthdays of yours to pass, I'm counting down each one." After which, presumably, she'll be of legal age.

The most popular post has Miki in a midriff top and jeans on the beach pointing upwards. Zhang Muyi stands disconcertingly two heads taller than her with his finger joining hers - a "kiss", of sorts. An overwhelming number of the 8800 comments show messages of support, wishing them good luck, and enraptured by their romance.
