To better express her feelings for Xiaolan, Tiantian decides to draw a big heart on the letter. But no matter how hard she tries, she can't get it right, and it frustrates her terribly.
Then her mother tells her, "A heart drawn with love has magic in it! Since our Tiantian drew it with all her heart, it will surely tell Xiaolan that you'll always cherish your friendship!"
