667 Love Letters was produced to commemorate the resumption of sales of Lipton paper pack series milk tea, which was discontinued in March 2022. 

The ad itself is titled 667 Love Letters, in reference to the number of letters the company received from Lipton Royal Milk Tea enjoyers between April to September 2022.
