How Have You Been, My Brother?

is the thirteenth episode of the first season of the Fruits Basket 2019 Anime.

Summary
Tohru Honda meets yet another Sohma, namely Ayame Sohma, the biological older brother of Yuki Sohma, and learns something about Yuki that she never knew before.

Plot
Ayame Sohma, Yuki's older brother, is the Snake of the zodiac and has arrived at the house. Whilst Yuki is displeased at his arrival, Ayame takes an interest in Tohru.

Taking her to lunch, Ayame divulges that the Sohma brothers have not been close for years. Part of this can be attributed to Yuki being isolated as a child and Ayame wishes to alleviate the current situation.

Although he attempts to, Ayame makes little progress in building his connection to Yuki. He is not deterred from trying and remains at Shigure's house until the next day.

Hatori has arrived to bring him back, having done so at Hatsuharu's recommendation. After he has left, Yuki does recognize that his brother wanted to improve their bond.
