My Friends is the 2nd overall episode of Tegami Bachi
Lag, Gauche, and Roda continue their journey. Lag starts to warm up to Gauche and Roda, but he is still intent on finding his mother and asks Gauche to bring him along to Akatsuki if he becomes Head Bee. However Gauche sticks to his duty as Letter Bee and does not want to have any connections with the boy.
Soon, Lag becomes upset and steals Gauche's shindanjuu while he's asleep to head for the capital, but is lost and falls into a sand trap by a Gaichuu Bucker. Gauche arrives in time to save Lag and shoots the gaichuu, but he misses as it's too far. They prepare for another shot and Lag reveals a spirit amber in his left eye, which strengthens the shindanjuu and destroy the gaichuu.
Later, Lag carries an injured Gauche all the way to town. Three days passed and Gauche has trouble getting supplies as the townspeople are wary of outsiders. Lag brings food and water before they leave. Lag and Gauche have a touching moment as Gauche finally treats him as a friend. As Lag bids farewell to Gauche, he shouts that he will be a Letter Bee like him someday. Five years later, Lag prepares to embark on his promise to be a Letter Bee.
